I can't say with 100% accuracy due to not having control over the valve job that may or may not be done, also any porting work that could have been in conjunction with using those valves and the also the amount of lift that will be used, and most importantly the lift rate that the Cam lobes have and of course the rocker ratio used which effects the rate of opening.
With D-port heads in stock form and less then .450" lift applied to the valve I would place the power reduction at 3 to 4 percent which would also produce a power band that starts to kick in at a 3 to 4 percent higher rpm.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
