Detailed Description

CNC Machined Cylinder Heads

We've taken something great and made it even better! Now our heads are available fully CNC Machined on both the intake and exhaust ports.

Part No: 200-1080 - Stealth Aluminum Cylinder Head - CNC PORTED - ASSEMBLED SINGLE HEAD (order quantity 2 for a pair)

All specs on the head castings and valvetrain hardware can be found on the specs page for our standard (non CNC) Stealth cylinder heads.

Port design by Jeff Kobylski at Modern Cylinder Head in Clinton Township, Michigan.

Over a pound of aluminum is removed from the ports during CNC machining, taking over 43cc's out of the port. This enlarges the intake ports from the stock 212cc's out to 255cc's! Because the automated machine which does the porting is fully computer controlled, it can produce results which are identical and repeatable down to accuracies measuring in the thousandths of an inch. This means all ports will be exactly the same shape and volume, ensuring the flow numbers are consistent and accurate for EVERY port on EVERY head.

Another view from the port window side of the intake port shows what a straight shot the intake port has. An intake port that flows over 320 CFM will put the average stroker motor well into the high 600 to low 700 horsepower range.

The exhaust ports are just as nice as the intakes.
