That may be the case with mine as well. I’m not there yet, I’ll cross that bridge when I get to that point.
I also read about using beehive springs to help but maybe that’s a Chevy thing or a bandaid and has its own set of problems when ya use em. I don’t know. When Brian at IMM prepped the Indy/RHS heads, he fitted them with beehive springs and those heads worked damn good.
