This isn’t my question, I’m not worried about compression ratios this is all stuff I understand, I’m asking if the closed chamber 302 castings will hit the dome on the piston (or 920 casting like I want but cannot find.
Second question is where to get a proper 318 head gasket as most available are cut to be used on a 360 as well so with this massive combustion ring I’ll lose the compression gains icakeewehxjabezsbrhjsbhd
