Thicker head gasket to lower compression

Post  strokedmyford on May 16th 2016, 3:30 pm

I have on hand a flat top 502 short block going to be used for a propane build that never happened. I have a customer wanting a BBF for his daily driver 4X4, he was wanting to run pump gas. I was thinking of using some 95cc edelbrocks, .080 head gaskets to get the compression down. My concern is using a thicker head gasket to achieve my goals going to cause other issues with the large quench distance? I don't have a camshaft yet but I'm thinking it will be on the small side for good drivability. Any thoughts or other ideas appreciated.

YES ... any more total quench clearance than about .065" will have almost no quench benefit at all.
