Probally to close What psiton type and materials are yours and how much piston to cylinder wall do you have now? My pump gas 518 C.I. stroker with .0065 piston to cylinder wall clearance was rocking over enough to make it look like it was hitting the edge of the pistons on the combustion chamber edges when warmed up (190F) and revved up above 7000 RPM with .035 cold checking clearances( make sure and rock the piston all the way to the outside of the block and the same on the inside(cam side) I increased the head gasket thickness .008 to get .043 minimum I was trying to follow the recommendations of using .035 with steel rods and forged pistons That worked fine on the iron, open chamber 906 heads, not so good when I swapped the heads to a set of close chamber Eddy RPM aluminum heads
