I like to stay at or under .600" lift on an engine that will see a lot of street miles. Maybe a little too conservative? Additional lift is pretty much free horsepower but the additional stresses start to worry me. Comments?
I believe that the Butler cam is slightly warmer that the Comp and with the little extra LSA should be just as streetable. Butler would be my first choice with Comp a very close second. I think Powell might have missed the mark on this one.

I bet in Powells opinion the Pontiac exhaust is choked, probably compared to other cylinder heads.
