The Lion III is made to be about 6.5± compression but is thicker than the stock head designs so it can be machined down if higher compression is desired.
Also, I have a Stipe cam, a Weber carb and the cast iron header from Snyder's on a fresh rebuild. This is a pretty balanced combination although it wants a lot of timing advance at lower RPM. I made a plate to limit total spark advance to about 31° at the crank but it wants at least 10° off idle or it will hesitate.
Just some more information to further confuse...

Gene,
Is your LSH III the head from Steve's Coupe?
If so that is the same LSH III head that I mentioned in post #37.
