One pair of 2.8" MCSA Intake runner CID BE Gen V LT Cylinder Heads CNC Ported, valve jobbed with 57cc CNC chamber.

These are our bigger intake port offerings and are best suited to engines running aftermarket plastic factory style manifolds, Holley Hi Rams, factory style blowers, and LME aftermarket intake manifolds. 

Heads accept factory length and diameter valves with factory rocker gear.

12MM ARP Nuts for studs to suit CID LT head part # is 300-8338. These have a .875" flange.
