CYLINDER HEADS - Pro-Port™ Raw & Semi-Finished Heads - Chevrolet SB2 & ROX
Chevrolet SB2 & ROX Applications
These new Victor series cylinder heads are serious competition cylinder heads designed for maximum effort dirt track and drag racing applications. They have been cast with extra material in the intake and exhaust ports and combustion chambers to allow professional CNC porting, along with extra material on the deck to allow for fine tuning of the combustion chamber. These high-quality castings are treated to HIP processing for superior casting density and extreme durability. Victor series SB2 is for engine blocks with 4.4" bore spacing and accepts GM SB 2.2 style valve covers only. ROX is for engine blocks with 4.5" bore spacing and accepts GM ROX style valve covers. Victor ROX head #777668 features raised intake and exhaust spring pockets and are machined to 1.450" diameter.
Please note: These heads require professional preparation.
