Increase Power and Improve Reliability on Your Chevy LS3 with Edelbrock Victor 11-Degree CNC 6-Bolt Cylinder Heads

Your boosted Chevy LS3-based engine makes loads of power, but it chews through head gaskets like it’s at an all-you-can-eat buffet. Conventional wisdom says to turn down the boost, but the hotrodder in you says it’s time to ditch your 4-bolt clamp heads for Edelbrock Victor 11-Degree CNC 6-Bolt Cylinder Heads and keep the boost pumping. 

The 6-bolt-per-cylinder design of the Edelbrock Victor heads distributes the clamping load over a wider area, providing a more secure seal against the head gasket. The additional clamping force also aids significantly in head gasket retention, preventing leaks or blow-outs in high-compression naturally aspirated and highly boosted, forced induction engines.
