Re: head to piston clearance

Can you measure the old piston, pin hole to top edge? Sounds like a 6v piston on the 12v rod, for the big dome? Shim thickness? Pics of piston and shims? Shouldn't need any spacers/shims.

Yeah i checked it was the head gasket, it looked like shims for adjusting head height, i guess i will assemble with the gaskets they gave me and i should be alright, thanks for your help guys skip
