Cometic will do a custom gasket for a minimal one time charge. I've had =
a Spitfire gasket made thick to make up for an over zealous block =
milling and another one with a wider piston opening. Once they make the =
design changes, they send you a PDF with the dimensions listed for your =
approval. When it's OK, they assign a part number and CNC it out. Design =
turn around is about a week and another week to make it. After the first =
