04-06 GTO LS1 Edelbrock Pro-Port Head
[61989]


$1,259.99
   Manufacturer:Edelbrock
   Description:Designed, engineered and cast with porting in mind, the newly released Edelbrock LS1 Pro-Port™ cylinder head is the perfect casting for any custom cylinder head porter.

This newly released LS1 cylinder head casting is the same high-quality casting that Edelbrock has designed for use in our own fully assembled, CNC ported LS1 cylinder head, soon to be released. We feel that this casting is so good and so durable that every LS1 cylinder head specialist will find this high-quality, robust casting the casting of choice when it comes to carving out their own custom ports.

Cylinder head porters and engine builders alike now have an affordable LS1 casting that will enable them to create new port configurations, never before possible with the thin, lightweight factory castings. The Edelbrock #61989 Pro-Port™ casting opens the door to creating small-to-large port configurations with 100% clean-up, producing high flowing, and high velocity air-flow numbers.

Features Include:

•Machined to OE dimensions to allow for an easy transition with existing CNC programs
•Tall intake short turn and small intake cross-section for modern, high velocity port designs
•Exhaust features extra bowl and short turn material to accommodate all exhaust port shapes philosophies.
•Extra metal and merged rocker boss pairs for improved valve train stability and support
•Extra material in the spring pockets to allow machining for larger spring diameters
•Heavy deck thickness ensures optimum gasket retention and material for milling of the deck for smaller combustion chamber sizes
•Newly designed internal water jacket allows for highly efficient cooling without sacrificing extra material and overall strength
•Versatile combustion chamber can be machined from sizes ranging 40cc to 80cc without fear of thin material
•OE quality powdered metal valve seats and Edelbrock proprietary valve guides installed
•Heli-coiled rocker stands and exhaust flange bolts holes
•Sold In pairs

These heads will be in stock soon!!
