The MAP Stage 2 service is our first cylinder head option that includes our porting and polishing service. We clean up the casting flash in both the intake and exhaust ports, improve bowl to seat blending, and unify all of the ports to ensure even flow to each cylinder! The end result is a fresh cylinder head that is ready for installation with a bit of extra airflow that is sure to free up some more ponies!

The MAP Stage 3 service improves upon our stage 2 cylinder head in two regards. We clean up the casting flash in both the intake and exhaust ports, improve bowl to seat blending, and unify all of the ports to ensure even flow to each cylinder just as we would in the stage 2 cylinder head service. Then we take it one step further with additional shaping and blending of the bowls and guide bosses for even more airflow. On top of that we upgrade the valve job from our standard 3 angle to a performance 5 angle for the absolute best airflow characteristics!

The MAP Stage 4 service improves upon our stage 3 cylinder head in many ways. We take the porting and polishing to yet another level (Stage 3 includes: clean up of casting flash, improve bowl to seat blending, reshaping and blending the guide bosses, unify and shape ports to ensure optimal flow) through more aggressive port work in the intake and exhaust ports, full combustion chamber reshaping and polishing, and unshrouding of the valve for improved flow on oversize valve applications. This is where we really start to see big improvements in regards to airflow and in turn horsepower!

Included Services:

• Clean / Hot Tank
• Visual Evaluation / Inspection
• Deck Resurface to High Performance RA Specs
