Do you have any horsepower numbers for these heads?

 

About two years ago i had it dynoed, it had 434 hp NA and 585hp N.O.S. with the T-Rex cam shaft, and LS6 intake. 80mm BBK TB.. .The heads are Hand Ported not CNCed for got to add that in. Very nice job and smooth.

The heads will bolt up to 04 GTO

 

damn wish I had that much cash to spend right now. seems like a pretty good deal
