Head gasket with turbo pistons

  1. #1
    Forged engine is being stripped down and will put in ARP head studs, but need a new head gasket.
    Ran a standard gasket and standard head bolts before and I'm pressurising the coolant at 270+bhp.

    The pistons are wossner pocketed jobbers. slightly oversized at 78.7.
    Unsure if head has had anything off before. Probably will have had.

    Closest Athena gasket thickness I can get to a stock thickness is 1.4mm. Favouring Athena with the fire rings. However their bore size is 80.50 when others are 80.

    Presuming this will be fine... or any other suggestions/sizes/ideas?

    Make sure that the block and head are properly flat.

    You shouldn't have problems at that power with a totally stock gasket, nothing 'upgraded' required.
