I put the head on and measured the gap between the head and the cylinder with a feeler gauge. .003 - .005. I believe the compression is sealed by the cylinder spigot pushing up into the head and the head gasket is there to seal against oil leakage mainly around the two drainback holes. The copper head gasket measures .035 and would prevent the cyl spigot from bearing on the head by .030. Is this not a problem or should I come up with a much thinner HG than provided? By the way, there was a curious note in the gasket package concerning the copper head gasket. They said to be sure to anneal it and install it immediately...if not done so in 30 minutes it would need to be re-annealed.
