Buying Guide
What should you consider when choosing 350 Chevy engine heads?
- Material: Aluminum heads are lighter and can improve airflow, but cast iron variants may offer different durability benefits. Consider weight, heat dissipation, and porting needs.
- Combustion chamber size and compression: 64cc vs 60cc chambers influence compression with your piston dish. Larger chambers may reduce compression; smaller chambers can raise it.
- Flow characteristics: Intake and exhaust port designs affect horsepower and torque curves. Match head flow to your cam profile, manifold, and intended RPM range.
- Compatibility: Ensure the head fits your block, bore spacing, spark plug orientation, and valve sizes (2.02″ intake / 1.60″ exhaust are common sizes for SBC heads).
- Intended use: Street, street-legal performance, or track-focused builds will steer toward different head types and finishings.
