those flow numbers seem to be a bit high for heads that have barely any work in them.... They need to work on the CNC program.

Did you look at their site and compare the stock and ported flow #'s?

That cam is close to what I had in my ls1 that I blew up. It was 230/240 613/608 111. I wanted to go into this motor fresh so I chose another cam instead of re-using that one.

FWIW: Your old cam would have worked very well.

Is the Ex valve hollow stem as well? If so, who makes it and how much does it weigh?

I wonder how good the hollow stem valves hold up to nitrous. Like a 200 shot or something.

I dunno, but I'll find out once the motor is forged.
