Big Valve Heads for Custom Engines
Power Flow Series Racing Heads
These heads feature High Tech 1 piece Stainless Steel Swirl Polished Intake and Exhaust Valves. A whopping 40 x 35.5 mm. In addition, each port opening is template cut to exacting gasket specifications for 1-3/8" exhaust systems and hand blended and polished. Then, for improved flow past the seats, each and every Power Flow head receives a precision ground 3 angle valve job and finally is hand lapped prior to assembly. Each head is finished off with special hardened keepers, heavy duty chromoly retainers and high r.p.m. valve springs.
