Aluminum Head Identification

Very nice.
What were the specs on the cam?
its a custom solid roller cam and off the top of my head I believe 248/252 at 50, and around 585" lift, 110 lobe center. might be a little different I just haven't looked at the cam box in years

***** update, just looked at the cam numbers and it's a tad tamer than I posted originally. Sorry can't give out my exact specs but it's relatively close. Pm me if you want to know more...
