Default Lift limit for LT1 head flow?
the cam im thinking of has .544 lift after 1.6 rockers, would this be too much for stock heads? it seems like from the charts i look at that the heads stop flowing well at .600 lift. but where is the actual limit?

Dont know the actual limit but you will be fine with the .544 which Im assuming you are taking that number from 503 because thats a .535/.544 with 1.6RR's.

There are plenty of people running larger cams than that with stock heads. I used to have a CC305 cam with stock heads, and just swaped in a of the shelf GM847 cam and the car ran 2 tenths faster.
