How much clearance did you have between the piston and head? Also what was the piston to wall clearances?
I didn't measure either one, I'll have to put it back together and check that.
From what I am seeing its touching all the way around it. One side maybe a hair more but its all the way around. First off Most stock applications the piston will sit .020 below the deck. These rods tend to put the piston flush with the deck. A gasket once installed is usually about .032. Under load and high rpm these rods can stretch as much as .030. Thats why I have always said .030 minimum between anything moving. Now if this .030 stretch is happening then your only have a .002 safety margin. Not enough in my book. What you need to rectify this is have a .035 to .040 thick Copper head gasket made. But if you look close you will see the piston lip in the carbon on the other side of head. Now you can take roughly .010 maybe a couple more off the piston and fix it also
Thanks for the info George. I'm going to put the short block back together and do some measuring. I figured with the stock gasket I would have plenty of room.
