GM Performance Parts SB-Chevy ZZ4 Aluminum Heads

Product images may differ from actual product appearance.

The L98 Corvette small-block was a break through in advanced-design and efficiency largely because of the lightweight aluminum heads that were used on that engine. GM Performance Parts now offers you that same cylinder head in one complete assembly that features a D-shaped exhaust port, high-velocity intake runners, and centrally-located spark plugs. The applications are endless.
