Good Alu Head Castings To Look For?
I am ready to pep up my '78 F100 w/factory rebuilt 302. I also have a '69 351W block in the wings to be rebuilt. I already have a Lunati retro hyd roller kit, cam and Holley 4bbl/600ish in the closet that I bought for the 302.
I was wondering what some good aluminum castings, new/used, that I should look at to do a head swap and leave the factory stroke/pistons on the 302 but also to use later when I get the 351W block ready to drop in. I did not rebuild the 302, but I would bet the owner, who was a mechanic, put the stock type with a valve relief back in it. Not sure how small I should go with the quench size... 58cc-64cc in using the stock type pistons using pump gas.
Any suggestions accepted and thanks!

Everything from the basic Edelbrock Performer to Dart Pro1, to AFR and TFS aluminum heads are healthy upgrades over any of the stock Ford heads, I'd suggest you look for something with 1.90/1.60 valves and 60-62cc chambers which will be small enough to provide decent performance on the 302 but not so small it would make static CR too high on the 351.

I would go smaller on chamber size to maximize the ratio on the 302. You can always choose pistons for the 351 to match the smaller chambers. 58 cc's are the norm for the smaller chambers, choosing from 60-62 isn't going to change that much anyway on a 351, it will though limit your choices in heads, possibly forcing you to skip an otherwise good deal. I bought Canfields when I went shopping ten years ago, was about to buy Brodix then, till the Canfield deal popped up. Never regetted the choice I made.

They claim the Twisted Wedge 170's do not require cut valves for lifts up to .550". My Lunati cam is spec'd @ .445"/.477" - so I should be golden.
I read through their install sheet... they want us to go through the whole clay molded combustion chamber with heads bolted down... so I gonna make sure I follow their install and check clearances.
Thanks for the heads up tho Paul!

I put on GT40-X heads on a 5.0L with good results. There were the X & Y version with the X version offering more performance which is what I used. Both were offered in 65 & 58 CC versions. I'm not sure how easy it would be to find a set but these heads bolt right up, use stock valve train parts, etc. Add a set of 1.7 RR with your cam while you're at it.
These heads were cast with a different combustion chamber shape then the iron GT40 heads for more turbulence and better combustion. For use on a truck and a mild cam these heads should work well.
