PIE SuperTune LA ProMaxx Cylinder Heads
ProMaxx Aluminum Heads
Level 2 CNC Ported
Small Block Mopar LA ProMaxx Heads - Level 2 Ported
Our Level 2 ported ProMaxx heads feature complete CNC porting to both the intake and exhaust ports. After the CNC port work is performed, we hand blend the bowls into the valve job for a seamless transition. We also perform a CNC pushrod clearance as there is normally a clearance issue with the pushrods and pushrod tunnels.
You must choose a spring kit in the options section.
The price for the heads does not include a spring package.
