.’89-’02Fire Ring gasket. .080″ thick, 4.560″ wire O.D.
-Must use studs ( we suggest IFG tool steel studs)
-Must verify head is flat within .003″ end to end-
For best results please have your head and block machined prior to installation for flatness. For engines under 800hp, cutting grooves in the head or block is adequate, but for higher horsepower engines we suggest cutting grooves in both the head and block
