barabar, why did you seem to need more clearance? From what I have read, it's not necessary. Add the fact that you coated the top, of the piston reducing the amount of heat soak into the piston. Then also the aluminum piston having a higher heat coefficient. Then an iron block if you have an iron block. Your clearance should have been fine.
