one other thought about the cost of the Chapman CNC'ing process.....

while i agree that they are a leader in this area, $2000+ for the port work is just too much money.
the ICH 572-13 top end package one of my friends bought got their CNC port job....which from an appearance standpoint doesnt look much different than the Chapman VI's do....and that was only an $800 option.
i think Chapman is trying to recoupe their investment with too few a number of pieces sold.
i cant believe the Chapman machinery takes 2 1/2 times as long to port the heads as the ICH equipment does.

i spoke with one of the bigger engine shops that does Busch and Nextel stuff, and they do their own CNC porting....and they said it takes about 4hrs for the machine to port an 18deg Busch head.
