 "Brand New" GM 602 Heads

Add 36 Horsepower to your ‘602 Crate Motor - Feel the Need for Speed!! The stock ‘602 Crate engine produced 349 horsepower @ 6,000 rpm. With our CTS “Under Cover Ported” heads the same motor made 363 horsepower @ 6,000 rpm. Torque also increased 18 ft. lbs at 5,500 rpm. Next, our CTS Crate Master Cheater Camshaft was installed. With our Crate Master camshaft the motor made 385 horsepower @ 6,000 rpm. Torque increased another 9 ft. lbs at 6,000 rpm. The combination of CTS “Undercover Ported” heads and CTS Crate Master Camshaft improved the motor 36 horsepower and 31 ft. lbs of torque. CTS 602 crate head with "Under Cover Porting" “Undercover Porting” will add 14 horsepower & 18 ft. lbs. of torque. With our CTS Crate Master Camshaft, the improvement is 36 horsepower & 31 ft. lbs. of torque. The ‘602 crate motor has “Mexican” style Vortec cast iron heads. Of the several different styles of Vortec heads Chevrolet produced, the “Mexican” head is by far the worst flowing. However, they do respond to our “Undercover Porting” procedures. We supply  "Brand New" CTS Under Cover Ported” heads assembled with our Look-a-Like parts. (Valve springs, retainers, locks and intake valves). Ready to bolt on. Bulletproof your ‘602 Crate Motor Valve Train Every racer who runs a ‘602 crate knows the valve train, especially the valve springs, are a real problem. The stock valve springs are too cheap and too weak for circle track applications. On the ‘602 crate motor, we are concerned about the valve spring pressure, or lack thereof, on the intake valve. Why the intake valve and not the exhaust? Well, the intake valve is heaver and will “float” before the exhaust. Anything you can do to increase the effective valve spring pressure will help keep the intake valves out of this destructive “float” condition. The “intake valve float” condition is problematic because the stock Chevy ‘602 valve springs suck, especially if you are trying to run the motor over 5,800 rpm. Install our CTS “Look-A-Like” Intake valves, springs, retainers and locks and you will not have to worry about valve float again. Our Complete New Ported Heads (pair) Include: our CTS “Look-A-Like” Intake valves, springs, retainers and locks-Ready to bolt on and Win! Heads are new not used cores-Your Head cores not required.

Yes, we can rework your new or used ‘602 crate heads. Sending your heads to us has never been easier! If you don’t have good head boxes, we will send you some. If you do not have a place to ship them, we will send UPS to pick them up.
