No, there is only one base gasket. I installed it myself when I put it together a few years ago. Unfortunately, I did not take measurements of everything at the time. I was just entering the loop-arena at the time.

The compression numbers concern me, too. But I don't have comparison data...only inklings that it should be up around 160???
Do you know the history of this motor? Years ago, we used to buy thicker base gaskets or stack two base gaskets to reduce compression on pinging motors with bad '80's gasoline. Any suspicion of that here?
