Cylinder Head
Why you need it:
Thousands of Fourth-Gen Firebirds and Trans Ams came with the LT1, and many of them have been waiting for the right set of cylinder heads to dramatically increase their factory horsepower. Thanks to CNC'd combustion chambers and bowl blending, these heads can produce more than 500 hp naturally aspirated and feature 54cc combustion chambers, 185cc intake and 67cc exhaust runners, and a 10.25:1 compression ratio with stock pistons. They come fully assembled with stainless steel 2.020-/1.600-inch exhaust valves, double valvesprings, chromoly steel retainers and locks, guideplates, and ARP 3?8-inch rocker studs.

These performance polyurethane LS1 motor mounts will outperform the OE units, and according to the manufacturer, "give you torque resistance for high-horsepower and monster-torque applications."
