Description

Ferrea 6000 SERIES
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.
Comes in a set of 12 Exhaust Valves.
This valve is oversized and require new Valve Seats to be installed in head for proper fitment.
For Honda / Acura J Series applications such as J30, J32, J35, & J37.
