Dart PRO1 Platinum heads are for big-inch, high rpm applications which favor peak power over low end flexibility.
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, studs, guide plates and seals.

Dart PRO1 Aluminum SBC 227 CNC
Dart PRO1 227 CNC heads are professional quality competition cylinder heads. We applied the airflow technology developed in our championship winning Pro Stock engine program to produce these state of the art heads. Every intake port, every exhaust runner, every valve bowl and every combustion chamber is 100% CNC machined on special dedicated PRO1 castings.
These heads are ideal for high compression, big inch small blocks and are great for supercharged applications. Standard valve angle and spacing are retained to allow use of off the shelf pistons and valve train components. Hardened exhaust seats are compatible with unleaded gasoline. Manganese bronze valve guides extend cylinder head life.
Comes with 1.550" valve spring use + .100" long valves
