I got these heads in on a trade. One head is brand new, the other was used and had 2 exhaust rocker stand bolt holes messed up. The new head I used to make a CNC program with and was on display at the PRI show in Orlando in Dec. Both heads have been made into a matching set and have been CNC'd with our 12 degree program. Our program requires the seats to be changed becouse of the larger valves we use. These have had the large CuBe seats installed and are valve jobed for 2.520 int and 1.810 exhaust. To have this CNC program done alone runs $2200.00 becouse of the extra labor of chaning seats on top of the CNC work. ( not to mention the $400.00 worth of seats that go back in them) But these heads are ready to be assembled, bare CNC ported for $3200.00 !!
