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.
