RB26DETT Stage 2.5 Cylinder Head

This head package is designed for engines making 1000hp.  The intake and exhaust ports are CNC ported and opened up to match the +1mm valves.  Combustion chambers are CNC machined to match an 87mm bore and can be either fully opened up or stay with the quench pads.  Here’s a break down of the head.
