The Hamilton 07-H-003 War Head Competition Cylinder Head for your 1989-1998 Dodge 5.9L Cummins 12-Valve is is designed specifically for heavy competition use. The casting features a thicker deck, thicker port walls, taller casting and optimized port shapes. In past cylinder heads, flow to cylinders #1 and #6 was less than cylinders #2-#5 due to casting deficiencies. On this head cylinders #2-#6 are identical. Due to ambiguous rules in some sanctioning bodies, #1 intake port was made slightly more narrow, but if you are having a port job done, enough material is present so that it can be machined to match the other 5 cylinders.
Due to the higher lift flow potential, Hamilton suggests their 62mm cam to make sure you are getting all of the lift possible to get the full benefit from the war head.
