    You can get shim gaskets thru ACL or have custom ones made at some engineering, metal and machine shops.
    Better off not cheating and change the pistons, cheaper in the long run.

    no need to lower comp its low allready shims and thick gaskets just cost power

    Ok, well have been running 10psi for a few years now with a powerdyne blower and have recently had the blower rebuilt and will be running 14psi from 3000rmp through a bleed off valve that is plumbed into the intercooler piping. It was recommended that i decompress the standard motor to accommodate for the increased boost levels. In everyones opinion would a standard series 2 v6 with Mace high ratio rockers, be a reliable setup with mods mentioned above. And a tune of course???
