If all my calculations are correct I need 64cc heads. Any suggestions on which to get? The only ones I've really found are the world products Roush and windsor sr. Lite.

 

if you need help with compression calculation, Give up the stroke, bore, piston dome size. gasket thickness and bore and head cc, then i can run it for you. 64 cc are a little big.

 

I'm actually trying to get a max of 8.5:1 compression. The motor will be running a roots style blower.

 

you will need dish pistons with a -6 cc inverted dome to get that low.

 

I allready have a shortblock with forged dish pistons. The 64cc is the number I got from the mechanic that built the shortblock for me. I did double check his math though.

The only heads I've found are the ones I mentioned at the beginning of this post, and the ford racing gt40 series.

Has anybody used the gt40x heads?

 

have you tired looking at AFR, or Canfield or Trick Flow or Edelbrock or Brodix heads?

 

I've checked the specs for the AFR, Trick Flow, and Edelbrock, and they are all between 58cc and 61cc. I'll have to check out Canfield. Brodix was the first I lookes at, the make some that would be perfect but are very expensive. Just like the mechanic in Mad Max says "Speeds just a question of money, How fast you wanna go?"

 

SAVE, SAVE, SAVE

 

you know you could always use a slightly thicker head gasket to reduce the CR a nad too!

 

could I get an extra 3cc from a head gasket?

I just went to canfields website. They are 58cc standard, but offer 54, 61, and 65. I think the 65 would work for me, and their prices seem great.
