At Noonan Ultimate Race Engineering, we don't just meet customer needs. We pride ourselves on knowing what you need, before you need it, and delivering next-gen scalable engine technology that will keep you one step ahead of your competitors for years to come. That's what makes us the market leader in the engineering and manufacturing of championship-winning cylinder heads.
The Noonan Mach I - Promod Blown and Alcohol Drag boat billet cylinder head was specially developed to meet the exacting competitive limits on the maximum valve size of blown racers.
Building a top racing cylinder head starts with a strong foundation. All Noonan Cylinder Heads are manufactured from high quality tempered billet material for outstanding durability in a light, economical package. Our refined billeting process is finished with 3D CNC machined contouring, which improves surface shine and resilience for an unmistakably elegant look.
With the Promod Blown and Alcohol Drag Boat Cylinder heads, we've taken this classic race-tested formula, and added new, innovative components that provide an instant boost to consistency and power of your engine performance.
For example, each cylinder head comes with robust spring oilers to keep your springs in great running condition, enhancing spring durability for improved overall reliability. We've also designed these Hemi fully billeted cylinder heads to accommodate 9/16" push rods and thrown in deck-faced O-ring and valve cover cylinder heads are virtually leakage-proof, even under the punishing conditions of competitive racing.
We can also offer, if require, Drain Back Drillings to suit late-model blocks. This painstaking process reduces oil retention in the top end of the motor, enabling oil to be returned to the sump or tank for more economical and reliable performance.
For us, racing isn't just a business, but a lifestyle. We pride ourselves on delivering success where it matters most - on the track - so we can take our clients' careers to the next level.
