Our Performance Rebuild suite of inspection and machine work is a great option for the value minded.  Even with GM's rough port work the OEM LS7 head is capable of producing 600hp+ with the right setup.  If you are building a 550hp+ setup, it is difficult to beat the value of bringing the factory head back into better than new condition.  Our deck milling, precision valve grinding and CNC'd valve jobs are a great way to pick up some power while ensuring your heads are ready to go for tens of thousands of miles.

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.
