Hey, I've been considering buying new heads for my 65' Falcon. As it stands now, I have the setup in my signature with 71' D0VE heads, and a blown head gasket. I believe one of the heads may be warped, and will probably need to be milled if I wish to replace the the head gasket. The motor also has very high mileage, although it is unknown.

The plan is to possibly build a mild 347 stroker or 351W next winter for the car, but for now the head gasket needs to repaired. I was thinking about mabye buying the new heads for the engine now, and putting them on the 302, and over the winter building another motor and putting them on it.

My biggest concern though is buying heads that are too small for the windsor I'd build, but I don't intend to build it up too much. My car sees a lot of driving, and chances are this summer and next with the new motor I'll be driving it over 300 miles to school, and mabye back and forth to work in the spring
I've been considering mabye Victor Jr. heads or Performers/Performer RPMs.

I guess one thing I need to be careful of is combustion chamber size, I don't want anything over 10.5 compression for the next engine I build, so I should steer away from anything below 60cc. That sorta makes me lean towards the performer with the 64cc chambers. Also, I wanted to consider the angle and positioning of the exhaust ports. If I put a 351W in the falcon, clearance with the headers will be very close (may have to use manifolds), and I know some cylinder heads make it easier or harder to put headers on.

Please if you have any suggestions or ideas, let me know. Right now I"m just sorta playing around with this idea, but I'm going to have to do something soon about my head gaskets. Thanks.

What about the afr 185's with a 61cc chamber. You can choose from 58, 61, and 69cc chambers and would match well with a 302 or 347.

Actually, I was thinking about the AFR 185's as well. My only concern was that the 185 might flow too much for me current 302 setup. I'm thinking it might be a good idea to actually put a bigger cam in and try to keep the compression ratio up with the 302 (and just use dished pistons with the 351W) to take advantage of the bigger heads. I just looked at the pricing for the AFR's, and its atually pretty reasonable. I'll probably end up going with the AFR's if nobody has any better suggestions.

I've never really heard of Canfield heads, I can't seem to find that much about them on the internet. It also only looks like they only come bare. Do they have a website?

Before you decide on a head I would finalize what type of engine you are going to build.I don't think there is any point in even running aftermarket heads if your going to use stock exhaust manifolds...Having said that you should be able to find headers for a 65 falcon (I'm assuming thats what you have) with a 351W.The 65-66 hedman mustang swap headers for example should work.Usually headers will give you more clearance than exhaust manifolds...You also might want to take a look at piston's for both type engines(stroker or basic 351W) to determine what cc head to get so you can easily get your desired compression ratio.

I think you're right about that. I probably should decide exactly what i'm going to build before I invest in heads. I think a 61cc compression ratio is exactly what I want. With dished/valve cut pistons with a volume of 6.5cc I'd have a compression ration of 10 with a 331, 10.2 with a 347 and 10.5 with a 351. Thats basically where I want to be.

Chances are, I'll rebuild the 302 I have as a 331 or a 347. That way I know my old headers will fit and I can reuse my intake and distributor.

So assuming I'm going to build a streetable 347 with 10.2 compression, a weiand stealth intake, long tube headers, full dual exhaust, and a mild cam, c4 w/ shift kit and low stall, etc. Would a AFR 185 be a good choice for heads? And would it be too much to run on my 302 for the time being?

Hey, thanks for the website. Looking at it, the Canfield 192 seems to be almost the exact same price as the AFR 185. Anybody know any difference between the two? Looking at the flow chart provided by AFR and Canfield, they seem to flow relatively the same. Looks like the Canfield may flow a little better on the Exhaust and the AFR might flow a little better on the intake.

Take a look at the Canfield CNC chambered 192cc heads. Average out the flow from .200 to .600. That's what you want to look at...not just the peak flow.

If you're interested in the Canfield head, contact Jay Allen at www.camshaftinnovations.com

I've seen people posting that they are happy with their Canfields from him.

Well, I'm not looking to go too crazy with the heads here or the next motor, because like I said, I'm trying to keep it streetable and I'm still in school. The AFR 185's is probably about as exspesnive as I'd like to go unless it could really be justified.

Hey, I've been looking at these Canfield heads, and Bob pointed out that canfield heads are made and sold in canfield ohio (duh), which is less than a half an hour from where I live. I'm thinking it'd probably save me some money to go with the canfield heads, but I don't know what combustion chamber size to go with. If I get the 58cc, my engine now will have 9.7:1 ratio, but a stroker motor will have 10.6:1, which is getting too high for me to run with a mild motor as a daily driver. If I get the 65cc, my engine now will have something like 8.7:1 compression ratio with a mild cam. Probably doesn't make that much of a difference, but do you think my engine would run well now and still have some balls with 8.7:1?

I'd like to go with the 58cc, but what can I do to keep the compression down with a 347? I suppose if I run dished pistons with a volume of 6.5cc, and a extra thick head gasket, that'll keep it around 10.5.
