Ferrea valves are a good idea when you are building an engine. The 6000 Series valves have dish faces which work well both in all motor applications and forced induction applications as well. The 6000 Series is the most popularly used all purpose valve upgrade in the industry.
We have seen multiple racers cut corners by leaving their valvetrain stock, and go to the track after spending thousands of dollars building a race engine with new pistons, rods, bearings, head gasket, cams, etc, miss a shift, over rev, and drop a valve into their newly built engine ruining everything. Usually when a valve fails and falls into the engine, its catastrophic and nothing can be saved.
In the big picture, the valves will be one of the least expensive pieces you could buy when building an engine, don’t cut corners on the valvetrain, it could be the difference between losing everything or not.
The 6000 Series Competition Valves are designed to provide excellent reliability in an environment of high spring pressures and roller cams, at a budget price. They have higher fatigue resistance and tensile strengths than our competitor’s best offerings.
To manufacture the valves we use our exclusive two-step slow forging process using EV8 stainless steel on both intake and exhaust valves.We provide a special heat-treatment and stress relieving process, along with hard chrome stems and friction-welded hard tips. We finish with a swirl polished head. The valves feature flow improvements to deliver the power needed for today’s sophisticated racing engines.
