Head Gasket Suggestions

So with "quench" can you still run pump gas? It seems to me with a .035 distance between the heads and pistons you would have an extremely high cr like 12s or 13s. Also what about the piston to valve clearance? How do plan that out ahead of time seems like you would be extremely limited on cam selection

The quench is in just one area of the piston-to-head clearance. All the computations that you go for compression ratio through still apply. You can have a deep dished piston with low compression ratio but still have one edge of the piston come up very close to the bottom of the head and create a quench/squish gap. Don't think of just flat top pistons.....

One of the ideas behind quench/squish is so you can run pump gas with higher CR.

Piston-to-valve clearance is an entirely different matter.
