so long as they are completely stock, you'll be moving backwards. not only are the intake valves smaller, so are the runners. what you gain in compression will not make up for the loss of flow.
Cold Air Intake, Muffler Delete, Vinci High Performance Dual Valve Springs, Hardened Pushrods, Yella Terra 1.85 Rockers, Some Hydropdipped Stuff, Strut Tower Brace, Some SS Badges, boost/vacuum gauge, fuel pressure gauge, some checkered stripes, drilled/slotted rotors, ZL1addons Stealth wickerbill, Ruxifey LED side markers
