Advanced Induction Cylinder Head Development
100% CNC'd 280cc GM LS7 Cylinder Head Package

The CNC'd GM LS7 head is adequate for producing average power straight from the factory.  However, it is an entry level part that suffers from the relative inconsistency of large scale mass production.  Our latest offering is an excellent option for someone who already owns the CNC'd GM LS7 cylinder head.  Without a great deal of investment we are able to apply a superior port design.  Significantly increased performance coupled with vastly superior finish and consistency make this a phenomenally attractive piece for high end builders.  We can accommodate any application from utilizing factory GM components to all out road or drag race packages.  From 600 rwhp daily drivers to 750 rwhp race engines, this is a versatile and proven performer.

Pricing is for work applied to a pair (2) of cylinder head castings and components YOU supply unless otherwise noted.  We are happy to build your heads with whichever spring kit, valve, etc. you would like.
