ALL  CYLINDER HEAD - Part Number 24502615
Cylinder Head 15-Degree Aluminum. Aluminum cylinder head for small displacement NHRA Drag Racing Competition Eliminator racing engines. The head is identical to the 18-degree head, except it is rolled by machining the deck surface at a 2-degree angle to remove more material from the exhaust side than the intake side. Valve guide holes are tipped 1-degree, for a 3-degree total valve angle. This head has smaller combustion chambers than an 18-degree head (35-37cc). Note: This is not a CNC-ported cylinder head. GM Performance Parts cylinder heads are created with GM premium-engineering, then cast and machined to our exacting manufacturing standards. GMPP cylinder heads are available as bare castings or complete cylinder head from service replacement castings to all-out competition applications.
