Optional Upgrades Available  (Please call with your needs and we'll work up a custom quote for you)

**There are many options and upgrades available for these heads from custom high-nickel seat work, porting/polishing, custom intakes and runners, custom spring/retainers.......so please feel free to call and we will try to free up a machine shop employee to speak with you about your specific needs** We can flow heads here in-house also to measure before and after gains.

***Note we do not typically O-Ring or cut Fire Rings in the Common Rail heads as the factory style gasket used in conjunction with head studs hold up well***
