Product images may differ from actual product appearance.

Performer S/B Heads
Designed for 302-400ci engine up to 1986, these aluminum heads feature 185cc intake ports and 64cc combustion chambers. The combustion chambers are designed to improve performance and retain stock compression ratios on 1970 and earlier small blocks.

Performer Centerbolt Heads
Designed for 1987-95 Chevy 5.7L engines originally equipped with centerbolt valve covers. These aluminum heads use the 1987-95 intake manifold bolt pattern. The high velocity ports work with either TBI or Tuned Port Injection systems. They maintain stock compression when used with the recommended gasket. These heads will accept the stock centerbolt valve covers or the Edelbrock aluminum valve covers, P/N 350-4246, 4247.

E-Series Heads
The E-210 cylinder head for small-block Chevy engines provides race-level performance while maintaining full compatibility with OEM equipment. It features larger runners for increased airflow, revised exhaust ports and larger diameter springs for higher lift camshafts, making them ideal for a spec series racer and larger displacement engines. The exhaust port flange is in the stock location to allow for the use of off-the-shelf headers and hardware, while the enlarged valves and ports support the power needed to compete at engine speeds of up to 6500 rpm. The E-210 cylinder head is capable of supporting more than 500 naturally aspirated horsepower, and even more in forced induction applications.

These unported versions of Victor heads for the professional cylinder head porter or engine builder As-cast ports have enough metal thickness to allow for CNC porting to different sizes Seats and manganese-bronze valve guides included (except #77539 and #77549), but not installed.
