What type gaskets are you buick guys running for the cylinder stage2 heads.I but complete gasket set from Duttweiler with the FEL PRO 1026 head gaskets with 4.090 inner dia. ring.Bore on on center block 4.030 with ARP head studs do i need to use the block to head dowel pins to keep the gasket centered between the cylinders.How big of a bore with the 1026 felpro gaskets?I will be getting ready to order my custom pistons with my setup.How much in the hole do i leave the piston in the block and ring gaps for top and bottom?My combo stage2 on center 4.030 bore,LA Billet 3.590 crank,carrillo 6.5 rods,buick stage2 heads 46cc.Which custom pistons to order JE or CP pistons?
