Well geeze you usually knock the carbon off first .

I've been racking my brain on this hemi domed piston business becuse it would not be the same with an offset combustion chamber .About the only way or one way might be to squeeze wax and measure with a  good set of calipers from the piston skirt .

I don't know if it would work or not .You'd have to have the piston face clean enough the wax would stick and oil the head deck so it wouldn't stick .

Macdizzy mentioned using some kind  of wax or clay but exactly what kind or how to slips my mind .
