Message Hi folks

My machine shop has screwed me over and told me to use a stock headgasket which i bought but it turns out they have taken so much off the engine builder says it will just go bang.

0.9MM has been taken from the heads,
and my new CP pistons are sticking 12 thou out of the top of the cylinder block.

Does anybody know which size i should use to get the compression ratios back to stock, or upto 9 maybe? looks like i'm going to have to get a massively oversized cometic gasket which is a shame as i already have 1.2mm stock nissan and 1.5mm tomei MLS
