For those that want an iron head that delivers serious airflow we offer the iron stealth head in a level 2 port configuration. This head delivers 290 cfm on the intake port and is capable of supporting over 500 horsepower. Level 2 porting features CNC porting of the entire intake and exhaust ports. The combustion chamber is deshrouded and all the CNC work gets hand blended. We also perform a competition valve job on both the intake and the exhaust.

One very important upgrade that we perform as standard practice is to install manganese bronze valve guides in place of the factory iron. This ensures longer guide life and we can run the guide clearance tighter to reduce oil getting past the valve stem. This is an important detail the our competition overlooks.
