    Gasket bore size

    I have 92mm pistons, I need a 2,35mm (0,092 in) gasket to have at least 0,8mm between piston and head, but burton only have it at 93,5mm bore, is it too much differenze in bore size? is there any risk regarding sealing?

    Compression ratio from calculator should remain similar, 0,06 difference between 92,5 and 93,5.

    Thanks

    In case you are going to use a Cometic gasket make sure you have the required surface finish of block and head.

    Yes, I'm also having the head skimmed just enough to have a good finish.

    Thanks!
