The pictures in post 12 show indention at both the top and bottom of gaskets. I pressure tested it before this last gasket change and it held at ~18 psi with a cold engine. And again, it's fine at temp, with easy revving. Purposely drove it easy everywhere last Saturday and it was okay (up to ~200* haven't been able to get things hotter than that). It seems to be when it revs hard that it leaks. Whether it's rpm on the water pump causes a spike in pressure or the short spike in heat from cylinders, I don't know.
Tomorrow I'll do a more thorough test with the tester to see if I can figure out more.
I used sealer on gasket to block, gasket to intake has a silicon ring around it you can see in post 12. I used to not rtv this gasket at all and never had a problem with it. And yes, there are no dowels in the china walls.
