Is it worth upgrading to RAM AIR IV Aluminum Heads?
Thinking about upgrading to Edelbrock RAM AIR IV Aluminum Heads this winter.
My set up currently is 455 bored .30 over, TRW Forged Pistons, 4X Heads with Comp cam ram air V and Nodular Crankshaft 9799103 Who is running 455 with aluminum heads? How much horse power would I be gaining? Can I run on pump gas 87 or 93? Thanks in Advance for feedback
