6567GTO you are right about the type of rings used and and what grit hone was used to do the cylinders. I remember using a standard 800 grit stone on my hone several years ago and installing Moly rings, took about 2 months for the rings to seat (this was before I knew better) Also something else that can cause exceessive cylinder pressure is not staggering the gaps on the rings I have known this to happen before, but this will also cause blowby. But for some reason I never had problems with blowing the dipstick back out.
