Healey 100-4 short block is assemblyed using flat top pistons. The Piston Crowns protrude .007" above the block surface @ TDC. I'm concerned if will cause interference with the cylinder head. The block surface was faced to ensure a flat surface, but maybe too much removed. My plan was to use a nos Mowag laminated Copper Head gasket. The Head Gasket measures .079" th. uncompressed. I'm using a Elgin fast street cam with .43" lift. The distance bwteen the Head surface & closed valve is .457". I don't plan on driving car hard & won't see redline very often.
I would assume I need to also account for piston growth from expansion @ operating temp. & maybe some connecting rod growth too.Taking these factors into account + .007" piston above surface - compressed Head Gasket thickness (amount ?), does the piston still have a safe amount of clearance to the cylinder head?
Does anyone have experience with this?
