Pro1 Chevrolet Big Block Head – 325.00 CC Port, 121.00 CC Chamber

Serious street performance, mild bracket racing, and marine. Over 7,000 RPM, 525+ cubic inches. Can be used on smaller engines with a tight converter. The PRO1 24 Deg 325cc delivers increased airflow at high valve lift for high RPM, big cubic inch engines, and still remains compatible with off the shelf pistons, valve train components, and intake manifolds. Long wearing Bronze valve guides, screw-in studs, multi-angle intake seats with hardened, radiused exhaust seats are standard. Best of all, our precision cast ports produce outstanding airflow without time consuming porting. Assemblies include Stainless Steel valves, premium springs, locks, retainers, guide plates and seals.
