I'm thinking about buying these heads: http://forums.corral.net/forums/show....php?t=1251989 but I think my compression will be too low. The combustion chambers have been CNC'd to 68cc. I have a 306. The valve reliefs on my pistons are the same as they would be on a stock 302 piston. My GT40P heads had a C/R of about 9.5:1 so these should bring me to around 8.7:1 roughly? Will my performance hurt because of such a low compression ratio?

 

run some boost now

 

Haha, That's what I want to do in the future. I don't have the money for it now though. If I buy and install these will I be ok running them?

 

It should run fine, might be down a tad on power n/a though, but it's a good deal if you plan on running boost later.

 

Yeah, I've made a deal with him already. I'll probably end up having them milled down to 58cc. That is what Woody at Ford Strokers recommends.
