i'll repeat it again , chapman is not a source for the head , i am going to go out on a limb here and guess that MP is marking up what chapman is charging for the CNC work .

a perfect example is the lift pump on the 98.5 - 2002 cummins , i can buy it from cummins for about 140 bucks , mopar , over 400 .

and like streetwize , if i didn't get a smoking deal on them i'd be waiting on the MP fire sale of these heads .
