    Surely Diamond or Wiseco has something in that bore.

    Try Armin @ Perry performance group.
    Some people use 2 head gaskets.

    Cometic will make custom gaskets. Bit pricey, but sounds better than running 2 gaskets.. Yes, no?

    I got my JE Lower compression pistons from Armin @ PPG. They are very nice, and I have over 90 hrs on them so far, no problems what so ever.

    how much boost you plan to run as the stock pistons (mahl) are good quality and good for 20 psi at stock comp ratio with correct fuel setup.

    I want to run over 20 psi but I will probably just use the Riva ecu and RRFPR and stay around 20-22 psi.........if I could find a ECM and someone that has a base map for my setup I would go over 20-22.........I'm not experienced enough to program the fuel/timing curve myself..........I am rebuilding my engine anyways, I would like to make it as bulletproof as possible while I'm in there.........thanks for the advise

    Dont go crazy lowering the compression,If you gonna use the correct fuel(octane) youll be fine.
    I have run close to 10-1 compression with 30+ #s of boost,Of course i ran 117 octane fuel
