Stage 1 cylinder heads are designed for performance on a budget. They produce excellent power throughout the entire RPM range, and work best with street/strip naturally aspirated applications, although they will work well in other applications as well. |
- Hot tank and thoroughly inspect cylinder heads
- Combustion chamber cleanup to improve burn pattern and increase flame speed
- Port match intake and exhaust ports to increase flow
- Resurface heads to desired compression ratio
- Pro Street 3 angle valve job
- Ferrea 6000 series valves 2.02” intake/1.56” exhaust
- Comp Cams high performance valve springs
- Lightweight retainers and machined locks
- Viton valve seals
- Set all valve spring pressures and heights
- Flow bench test with print out
-
Fully assembled head, ready to bolt on (core required)
PLUS:
- Custom ground Competition Cams camshaft, completely custom designed for your goals
- One piece chromemoly pushrods

Stage 1X cylinder heads are designed for nitrous or supercharged applications. The exhaust porting in emphasized in order to get all of the extra exhaust volume out that nitrous and superchargers create. Intake porting is similar to our Stage 1, while the exhaust gets the Stage 2 treatment. |

Stage 2 heads are all about horsepower. They were designed with one thing in mind, and that's to squeeze every last drop of horsepower out of your high power street/strip setup. Although they work best on smaller displacement (less than 382 cubic inches), we've had these heads make some great power in big cubic inch monsters as well. |
- Hot tank and thoroughly inspect cylinder heads
- Complete combustion chamber porting, maximum burn pattern and flame speed
- Fully unshroud combustion chamber
- Fully hand ported intake and exhaust runners
- Ferrea 6000 series valves 2.055” intake/1.60” exhaust
- Port volume matched to application-supercharged, naturally aspirated, nitrous etc.
- Pro Race 3 angle valve job
- Resurface heads to desired compression ratio
- Comp Cams high performance dual valve springs
- Titanium retainers and machined locks
- Viton valve seals
- Set all valve spring pressures and heights
- Flow bench test with print out
- Fully assembled head, ready to bolt on (core required)
