for tailored applications. These heads feature raised exhaust ports to improve flow efficiency and the deck
includes extra material to allow fine tuning of the combustion chamber. Supplied with reamed and semifinished
valve stem guides, and no valve job – final guide sizing and valve seat finishing is required before
use. Maintains the factory valve cover rail and will fit Edelbrock Victor SB2 Spider manifold #2862. These
heads have also been HIP processed for improved quality and strength. This head will only fit SB2 engine
blocks with 4.4" bore spacing.
