    Bigger head gaskets, who sells them?

    Like tittle says. I have a new to me darton sleeved block with way bigger bores. Cp pistons that came with it are cp103.

    Whom might sell this head gasket. Ohh not sure if this is pertinent but head studs are 1/2 arp... Thanks in advance guys. The stock head gasket looks like a joke on this thing. Like putting a VW 1.8 head gasket on a big block Chevy.

    103 mm bore? Stock head gaskets may not be large enough...

    Is this not a stock replacement? I have a 103mm bore if not mistaken. Haven't taken measurements yet. But stock head gasket sits in the combustion chamber with this port.

    Cometic can make any head gasket you want. They have different thicknesses in stock bore size so I'm sure they could make large bore ones.
