350 Head Gasket

Dave Gantz · 12-27-2013, 04:43 PM

I have Goodwrench 350 in my truck. I'm putting head gaskets on it. (I actually pulled the motor to re-gasket and re-seal the whole thing.)
The thing probably has 8.0 to 1 compression, I'm guessing? I don't want to give up any. The gaskets that came off it are about .017". I have a pair of GM #10105117's, that are supposed to compress to .028" (they're .034" now) . Then there's the Felpros's that are about .039", compressed. I see these: http://www.summitracing.com/parts/FEL-1094/ are .015", but are for a 4.100" bore. What's my best option? I'd like to keep as much compression as possible, without doing anything besides the gasket. Is there a direct replacement for what I removed?
