Thicker gasket worth it?
Is it worth pulling heads off while we are close, changing gasket for lower compression.... or leave it alone? Value?

The mixing of the air/fuel within your engine's combustion chamber, and its flame propagation characteristics are highly dependent on the "squish area"; the area where the piston squeezes up against the cylinder head: the gap there is carefully designed to be small enough to cause a large amount of gas rushing out as the piston comes to top dead center, but not so much that turbulence becomes excessive and combustion inefficient. Squish has a lot to do with a particular engine's tendency to detonate.
Every tuner I have spoken with, every engine shop I've seen quoted, and every book on internal combustion engines I've read warns against changing the squish area; yes, you can do it, sure many people have done it, but that is not the correct way of changing an engine's compression ratio.

Sincere thanx for the advise.
Makes bigtime sense not screwing with quench as designed.
I am going to forget the head studs as well....saving dough is good if work is not needed.
