As you might have guessed, the cylinder heads are definitely impressive. They're based off the Corvette LS7 head, but they're fully CNC-machined with 275cc intake ports, 89cc exhaust ports and a 70cc chamber. Intake valves are 2.200-inch diameter titanium jobs from Del West while the exhausts are lightweight sodium filled pieces that measure 1.610 inches on the head. We're not privy to the flow numbers, but we can only imagine, they're over-the-top. Note, too, the use of head studs. This is a serious piece. Stock Eliminator rules prohibit porting of any kind and chamber size must remain stock. Any valve job is permitted.
