We just put on a set this past week on a car that has .590 cam with 915 heads with a crossram. The car only made 2 passes with this combo and went 11.00 @120mph. Put the cnc heads by jeff on and went [Email]10.47@127[/Email] at cc. in colombus this past wkend. Jake
Nice gain.  Did the 915's have any port work done to them?

Yes they had a nice port job on them and they had 2.14/1.81 valves. They also had a maxwedge intake port.

Are the intake valve seats big enough to go 2.19 valves, and is there enough meat in the throats to match?
What is the cost for a cnc ported set from mch?
