RHS 215 heads

Unfortunately all of my damaging on the bumper passes from last year and this year either were recorded from the incar video camera or not recorded at all. I did get one on video from YWN broadcast live on the internet that I still have (saved the video clips)from the Sept Toronto Motorsport OSCA meet in Canada where I had all 4 wheels off the ground at the same time and had each individual tire hit and bounce off one at a time. It was on the left side almost totally on it's side about to roll and it sat down around 330' and continued bouncing from tire to tire until it got out of video camera view. These heads make power, be prepared to have traction issues and they love RPMs even if your cam is small. $800 is a steal especially for the alum 215s. I paid $615 plus shipping for my bare iron PT 215s and I was happy and still am happy with them even after these years of using them. I'm making more power than I should with a small street cam and running waay more RPMs thanyou would otherwise think with 392 cubes and a small cam. They definitely have potential and will stomp the crap out of even the best ported Windsor Sr or N351 heads and can run away from AFR225s when ported properly. I helped a friend build up a 418 using 4.030" flat top pistons and angle milled alum PT 215s heavily ported with angle milled decks for 48CC chambers. The cam is 266/275 at .050 with .730 lift and 112LSA on a 108 ICL and it made 760HP at 7500RPM and held on to 7900 within 10HP before falling off. Just a Super Victor that I opened up the plenum on and hogged out a Dominator 2" adapter and he bought an 1150 HP Dominator (not a 9375 1050 like mine is) and 2" Kooks headers w/3.5" collectors. His PTs are larger than mine with 246CC intake ports and 2.10/1.625 valves. Mine are 237 with 2.08/1.60 valves and much smaller exhaust ports. They can rock when prepped and I believe Jay Allen will surprise everybody if he ever builds a hard core or max effort 400+ cube stroker using these heads when ported good. I don't think 800hp is out of the question. I am definitely going to get a Jay Allen cam so I can see how much power my 392 can really make. These are great heads even for mild performance 347s or 351Ws with room to grow in the future without giving up anything down low as long as they aren't ported other than a light clea-up. I am using the as delivered valve job that came on mine and severe duty valves from MME Racing which might be Engine Works valves and they are +.200 long for 2.05 installed height with no spring cup using my iron heads. Alum heads will have about a 2.0 installed height with those valves since the spring seats will be at least .060" thick. The machining quality was great and the casting is surprisingly nice. I do notice that only Isky adjustable guide plates will get the rockers perfectly centered over the valve tips and the Ford roller rockers are a little too long and will ride near the outer edge of the valves toward the intake as opposed to the SBC rockers which put the tips directly center on the tips but I am using the Ford Angus Racing 1.72s anyway for 3 years running 7800+RPMs without any issues or problems what-so-ever. 8000 against the chip during every burnout in 2nd gear. Great heads for the price. Now I want to try a Dominator flange 351W intake from CHI and see what it does but $600 is a lot of money to just try something that may or may not work better.

Got a set coming at the end of the week. I'll get some pictures up soon as they get here. This set came from Livernois Motorsports.

Did they say how many sets they had left?

Did you get bare castings?

The geometry on these sets up better with the sbc rocker also. +.100 chevy valve is not long enough if your planning on a REAL camshaft

No I didn't ask how many they had left. And yes I got bare castings. I was planning on a +200" valve myself. I would prefer a 1.90-1.95" installed height. The 1.80-1.85" with the +100" valves doesn't cut it.

Can't wait to get these things setup and in a car. A cam from Jay's really going to do a number with them. Thing is anymore, making enough power to split a stock block is easy. It's going to be up to me with the build and light internals to try to keep the block in one piece. I'm keeping the compression at 10:1, light pistons and really light rods, plus it will only be raced a few times till I get the $$ together for a Boss block. If I waited it would be more cost effective...but who wants to wait? Damn impatient kids!

Ok, time to clear some stuff up.

I talked to RHS today about the 215cc Pro Toplines being sold by Livernois Motorsports for 250$ each bare. RHS verified what Livernois told me. These heads are NOT Pro Toplines. They're the FIRST run of RHS heads, and are cosmetic blems. Meaning a bit of casting flash, etc etc. These heads WORK exactly the same way, same flow, same power. This is from the company who made them, and sold them to Livernois.

These my friends, are a screaming deal.

HHmmm,

All 4 sets that I have from Livernois are cast Pro Topline right in the head. 1 set came in a Protopline boxes , the other 3 came in plain brown boxes marked "blem"
Dave , their parts guy told me they were old inventory from Pro Topline.
Either way they are a awsome deal, like you said.
It would be insane to by the Procomps when these are the same money.

The blem issue on the ones I have is the deck surface. When they were finished, the cut did not take off all the casting roughness. It left the surface with microscopic imperfections. It's absolutely a non-issue, its all cosmetic.

Hmm, a friend of mine, Jack just picked up a set last week. They have nothing cast in them. This doesn't surprise me though. I mean, look at it like this. RHS owned ALL of Pro Toplines inventory once the sale of the company was final, these were cast with the PT logo. They had also run their own first run of heads by then (or shortly after), these had no logo, whether by a lack of a 'design' or incomplete molds. They probably sold the 'cosmetic blem' Pro Toplines, with the 'cosmetic blem' unlabeled RHS heads to Livernois, This would explain why the RHS guys simply said that all the heads they sold were cosmetic seconds. The nonfunctional ones were destroyed.

Here's a link to the discussion on sbftech.

(copy and paste, the comma screws up the link)

Like I said, when I get mine Friday I'll get some pictures up.

Well I picked up my heads. Here's a quote of the post I made over at sbftech.com about them.

Hey Jack, told you I'd post up some pictures of my 215's soon as I got them...got busy though lol.

Anyhow, they're in great shape. VERY little cleanup work will be necessary, and even that is a preference, nowhere near a necessity. Lighting in the garage sucked lol so excuse the pictures. The transition from the worked area where they blended the bowls to the seats is actually very smooth, no ridge, the pictures make it look like theres a step. Also, my decks are extremely clean.

Oddly enough, mine DO have the Pro Topline cast near the bottom outside head bolt. I know yours have nothing cast there. Other than that, mine are exactly the same as yours.

All in all the casting's very clean. There's a bit of roughness in the exhaust ports as you can see in one picture. The intake ports are extremely nice. When compared to my friend's RHS heads FROM RHS, there is NO DIFFERENCE. None, nada, zip. We even took some measurements. Port dimensions between heads are AMAZINGLY precise. His also have rough casting in the exhaust. These heads even have the rocker stud holes helicoiled. Many top name heads do not. I was told some of them have porous decks. Mine do not. The decks are very smooth, and the machine work clean. If my Canfield intake quality is rated a 10, I'd consider these an 8-9. All in all I'm very happy with them. Soon as I order my valves, I'll be taking my set down to have a port flowed. 4.030" bore, 1 3/4 or 2" pipe on the exhaust. I will also be having them flow the same port with my Canfield intake bolted on. Can't see it being much of a restriction though =p.



















By the way, Livernois only has about 8 sets left. If anyone else wants a set, I'd order them now.

Cris :smile
As was said, I'm very very happy with them. For 500$ bare, these can't be beat. Here's some pictures with them on the block.
