I have built an new 393 ci. motor using Pro-Comp victor jr style heads (aussie heads) w/ 2.02/1.60 valves & 215 cfm intake ports and 60cc. chambers. I don't know the recomended spark-plug length or even the recomended plug for these heads. Can anyone help me? Peet, in N. Carolina.

I got a set and these are the instructions given:
"The heads will require Felpro 1262 intake gaskets, Felpro 1486 exhaust gaskets, Suitable head gasket and head bolts for aluminum heads along with longer pushrods compatible with guide plates. Champion RC12YC Spark plugs or equivalent should be used. "

I got a set of these. Very satisfied for what I paid. No problems if you run +.100 valves designed for a chevy head. Ok, I will have to do a little port cleanup and tweaking, but saving this much over Edelbrocks is worth the try. With Comp spring locators to fit, 1.55 springs, Comp 10 degree superlocks and lash caps, I ended up within .010 of nominal spring height, a set of Crane Gold 1.6 "chevy" rockers gave me excellent valvetrain geometrywith NO pushrod clearance problems. I've seen posts where everyone complains about poor quality, bad grometry, etc... If you bleed Ford blue and ony will use "Ford" parts from the aftermarket, you will have GREAT problems. Use chevy rockers, the grometry is built in for them. the only problem I have now is what gaskets and headers to use. I bought a set of shortie headers. The pattern is for Felpro1415, 1.25" X 1.48" The pattern on the heads is 1.360" X 1.40" , not the normal rectangle. Felpro 1486's seem to be dimensionally correct, but where do you get a decent set of headers to go in an EARLY Stang (1970) that will fit these ports without blocking 25% of the port, or having to cut up new headers, custom a flange plate, etc... Anyone have any luck finding headers for these heads, AFR's, Brodix's or other large exhaust port heads without shelling out $500 - $700 for accufabs or custom Performance Racings headers?? What about hedman Husler 85007's or 85003's ???

Mine were 900.00 complete with 2.05 intakes, 1.60 ex, 60cc chambers, 3/8 studs and guide plates, delivered.
Search ebay for strike force heads. The castings are supplied by procomp but stamped PBM strikeforce. They are identical.

Good luck with your Pro-comp heads guys! Down here 99% of us aussies wont touch they're gear and I would personally shell out the extra bucks for the genuine article! Be it Edelbrock,Msd,CHI,AFD or crane!
They do more than just develop a quality product, they also dont take shortcuts in the quality of the materials used to manufacture the items so in the LONG term they dont get a bad rap for an inferior product!
BUT having said that I have not heard much feedback on the SBF head only the CHI copied cleveland head from Pro-comp that was on display at this years summernats and the general comments were of junk casting qualities and overall finish of the head but praise of the cost.

A friend of mine bought and installed a set of the exact same heads. His 393 is identical to the one I built a few year ago (and grenaded). Cams are even the same...in fact...his cam IS the one that was in mine. Only difference between mine & his is the heads.
I am not impressed by the Pro Comp's performance compared to my Victor Jr's. His is down some 10 mph compared to my old POS combo. That's close to a hundred horsepower give or take.
He's going to put a set of 205's on it & see what happens. I bet it wakes up....
Only thing I can visually tell wrong with the pro comps is that the ports are in no way anywhere close to the Jr heads that they supposedly mimic. The short turns are hideous as well. They can be ported to work....but heck, for what they cost, you shouldn't have to port the dang things! I paid $900 exactly for my Jr's when they first came out (bare with valves) and I still have them....and they still amaze me at how much power they're actually capable of when everyone says that they're junk.

Pro Comps are actually chinese cast heads. ProTopline (Pro Action) were the aussie made heads that CompCams bought out of bankruptcy and moved to their RHS facility. Not the same thing.
My experiance with ProTopline heads is they were a really good head and I cant imagine RHS changed them for the worse.

Pro Action were Kiwi heads, not aussie heads (check out their old logo, it's a kiwi not a kangaroo!!). Their factory was 80 miles from my home. A heap of imperfect castings came up on our local internet auction web site just after they went under. Glad to see they will live on through the comp name.
When I had the ProComp 210's and used Felpro 1011-2 head gaskets. There is a better deal if you follow this advice:
*1011-2 head gaskets from Summit are $36.95 each if you order Ford racing part# M-6051-A302 from Summit you get a pair of felpro 1011-2'(they have 1011-2 stamped right on them) for $29.88 the only difference is the package.
I used head bolts with no problems. Of course studs offer better clamping.
Oh, I ran the ProComps for a couple of years and decided that they left a lot of power on the table. I swapped them for name brand heads and gained a full 50+HP. Hopefully the pair you have do not have the common problems of rubbing pushrods and leaking valvecovers due to a poor design.
