Maximum Performance, Bracket Racing, Heads-Up & Super Classes over 7000 rpm, 525+ ci

PRO 1 aluminum big-block cylinder heads deliver out-of-the-box airflow that beats the competition - at an unbeatable price! Specifically designed for street performance, bracket racing, and Super eliminator engines, PRO 1 heads make Pro Stock airflow technology affordable for every big-block owner.
Inspired by our championship-winning Pro Stock designs, the PRO 1s race-proven features include rolled valve angles, improved spark plug location, extra-long intake valves, raised exhaust ports, and fast-burn chambers - yet the PRO 1 can be used with off-the-shelf pistons, valvetrain components, and intake manifolds. You get more power for your money with PRO 1!
Using advanced manufacturing techniques, we cast the PRO 1s ports with incredible accuracy. This precision casting technology duplicates the contours that were previously available only in hand-ported cylinder heads.
PRO 1 big-block heads are available with a choice of three different intake port sizes - 310cc, 325cc, and 345cc so you can match the runners to your engines displacement and rpm range perfectly.
