  • Head gaskets for 94mm bore...

    We know the VG33E stock bore is 91.5mm and as it turns out, I've got a set of pistons that are 94mm. Unfortunately, Fel Pro head gaskets have a fire ring that's almost exactly 94mm...and will likely leave 0.0005" overhang into the combustion chamber. Anyone know where to get a head gasket with a larger fire ring?

    I can't answer on where to find them but, you're talking half a thousandth, I would think you could probably hand ream that tolerance out, unless it squishes out more when compressed.
    I mean it's already Fel-Pro, (kinda already known for failing on these motors) so i might question their stamped metal tolerances too.
