Haha no problem man!
Assembled the short block today. Gapped the top rings at .0024 and the bottoms at .0026, rods and mains all came out right at .0031/2. Also happy to report that the dome clears the .060 milled 862 heads with .040 headgasket. Progresssssssssss

Nice.......clearance is the reason i didn't go with a dome piston. The ones i found when i bought my mahle's were not to be used with mild heads. The mahle's was alot lighter so i figured it was a fair trade off.

port matched to the intake
removed the rocker bolt hump and smoothed that area a lot.
blended the seat lip into the bowl, smooth as glass in the transition.
removed the swirl ramp and cleaned the area up on each side of the guides and bullet shaped the guided.
same with the exhaust side, bullet shaped the guide, cleaned the whole port up and slightly gasket matched the sides and roof of the exhaust port while leaving the floor alone except for polishing it.
there is is a pretty decent lip around the valve seat in the chamber. I’ll go get you a picture now.
