The L83 Gangster Cylinder Heads are changing the game in the world of head flow on LS Engines. The heads are a factory GM casting that have had some magic touches put on them from the team at Frankenstein Engine Dynamics and KPE Racing to make them bolt on a LS engine. Sold as a pair.
These Heads Feature:
Manley L83 Race Flo 1.930" Intake Valves
Manley L83 Extreme Duty 1.560" Exhaust Valves
PAC 1209X Valve Springs
CNC Ported by Frankenstein Engine Dynamics
Note: These heads will not work on an LT Block, they are modified to fit an LS engine block only. Will also require a L83 head swap camshaft.
