I'm still waiting for my pistons so I spent a minute and drew up the head and barrel gaskets in AutoCAD. I made some time at work today

, cut and checked them for fit and then made a 2mm thick aluminium base spacer. This should give me 8.35:1IMG_4174.jpg
I did a quick dummy up to make sure the chain was long enough to get the cams back in, it is but only just. Unfortunately I loose my squish band but until I go for a thick crowned piston that I can dish I'll run this way. If I have any head gasket problems I'll cut one from copper now it's drawn up. So running about 8.4:1 can only mean one thing....more boost.
