Below you will find listings for 454 heads.

Introduced in 1970 the Chevy big block 454 actually had 454.2 cubic inches. The LS5 version of the engine which came in the Corvette put out about 390 horses which is just ten horsepower less than the base C6 Corvettes of today. The engine also came in a much more powerful LS6 version that put out somewhere in the neighborhood of 450 horsepower which by today's standards is reaching Corvette Z06 horsepower levels.

In the early 70's like all the other General Motor's engines, the 454 started declining in power with the 1971 LS5 just producing 365 horsepower.

Depending on the model, the 454 came with both rectangular port heads that had 2.19 inch intake valves and 1.88 inch exhaust valves or oval port heads which where fitted with the smaller 2.06 intake valves and 1.72 inch exhaust valves.

A wide selection of heads are available for the 396 big block including aftermarket versions.
