MAXIMUM ENGINE RPM:

TRACK:

DRAG:

6800 - 7600

8000

NOTE: Maximum RPM depends on engine the stroke being used. The specifications listed here are for a Blue Printed 3.480-inch stroke engine.

NOTE: See Piston Speed vs RPM

CYLINDER HEAD GASKET:

PRODUCTION GASKET:

0.018-inch approx.

Steel shim with raised beads. For stock and mild modified.

STAINLESS STEEL SHIM:

0.017-inch

Designed similar to production except for the material. Recommended for HIGH PERFORMANCE racing engines and marine use where Maximum power is not used for long periods

STAINLESS COMPOSITION:

0.039-inch

Constructed of two layers of stainless with composition material between. Suitable for racing and marine use. Use on 4 and 4-1/8-inch bore blocks.

NOTE: All head gaskets should be installed with a commercial head gasket sealer. High compression engines may benefit by using aluminum paint for a gasket sealer. Steel shim gaskets do not need retorquing but all sandwich and composition gaskets should be retorqued HOT or COLD or as specified by the manufacturer .
