Ok. I understand that If I run the stage 3 head with 2.08 1.60 valves on a 3.906 bore with a 383 that I will have valve shrouding issues. My question is comparing to the stage II which is 2.055 and 1.57 valves, If i use the stage 3 heads which have 2.08 intake valves, on my 383, will I make LESS horsepower than if I was to use the stage II ls6 heads. Will I make the same, meaning bigger valve but more valve shrouding evening out to the stage 2 horsepower? Will I make less horsepower using the stage 3 than I would using the stage 2 head?

Factors: using a 250's duration at .050 cam with a 640's lift.
Factors:Might be changing to an iron block anyways later, but not this year.

Any help would be appreciated. Dyno numbers two with a 383

What do u mean I won't like it. Do u mean throttle response? What about horsepower and torque. Remember I am not interested in low end power or low end torque. My converter stalls at 3000 and flashes to 4500 plus I have 4.56 gears. I have no use for low end torque or horsepower. I am more concerned with high end horsepower and high end torque. I will be reving to 7500 on evry gear plus a 200 shot
