Our Ported LS7 Cylinder Head Package begins with the disassembly of your LS7 Cylinder Heads. We’ll then bead-blast and clean them, followed by deburring any rough edges. Next, we will install extended manganese bronzanium 90 guides for added durability.
Next, we’ll take your OEM LS7 Titanium Intake Valves, inspect them, and then reapply their crucial coating – restoring their silky smooth valve action. If your valves have been damaged, or you just want them replaced, we offer replacement OEM LS7 Titanium Intake Valves. Next up, we offer a couple options for your exhaust valves from Ferrea (depending on NA or forced induction build).
Of course, a cylinder head package wouldn’t be complete without our CNC porting using GPI’s hand-developed port program!
The port and chambers are carefully designed to provide the best combination of high flow capabilities and improved port velocity. This combination provides excellent horsepower gains while maintaining a strong torque curve. GPI’s LS7 cylinder heads are CNC ported in house to insure that exact tolerances are maintained.
Lastly, we offer several valve spring options to meet your needs, complete with reassembly of your cylinder heads and return shipping!
