The specs I have located for the 190e 8valve engine are minimal cylinder head height 97.8mm, mininum block height 292.35 mm. The question I have is if the head is a smidgeon thin, say .o8 mm (97.72mm), and the block height is at minimal thickness, how can I tell what the clearance with the pistons will be? If enough? If I assemble without a head gasket and no tapping occurs will that be good enough? I am aware that I may need an offset key for the cam.
