1) Full Radius Valve Job - The most critical, high velocity flow around a valve is right at the valve seat. The full radius valve job focuses on this area. Performed on a Serdi 60 machine utilizing our custom-designed tooling, ensures that valve edges are smooth for the best flow. The valve height is kept at a standard so we don't loose compression ratio. Many times we can achieve a better seal than at the factory. A full radius valve job alone can yield approximately a 3% gain in horsepower.

2) Porting - In the very competitive world of performance, the manufacturers have made ports more efficient. Because they have other parameters to consider, the engine becomes a restricted package that adds some negative shapes to the ports. Correcting and keeping port volume on target, we do not cut certain areas of the port. Maybe not as pretty as a "polished" head, but definitely faster.
3) Components - We offer a full line of valves and valves seats for optional larger ports. Other components include larger tappets and larger valves with options of titanium, stainless, DLC coatings etc.

We custom fabricate valve seats utilizing an aluminum bronze alloy.
This makes for a happy marriage between seat and valve where no erosion of valve seat or valve face occurs. |
4) Springs - Often overlooked, proper springs are an important part of the valve train. We
custom-order our springs from the largest automotive spring manufacturer in the world. Every spring is chrome silicone wire. Every spring is magafluxed and shot-peened to ensure
integrity. Some shops fit existing springs into a head. We design springs for each application.
5) Cams - Custom cams are an integral part of any serious high-performance application. Cams can compliment porting and larger valves tremendously. Lift and duration are important but ramp speed is the real science. We have many cam profiles to choose from for practically any application. Many are in stock.
