How much hp would I gain swapping my 853s for a set of stock LS6 heads? 25 rwhp? I posted this up in the dyno section but haven't gotten any replies in about 3 days. I would probably do a cam swap and an underdrive pulley at the same time. Car is an A4. Is it fair to say that I should pick up around 70 RWHP from this swap(cam, heads and pulley)? I haven't decided on a cam grind yet. Still debating. Car will have a 3600 stall though.

On the cars that I have done like that Ive seen any were between 18 to 28 rwhp depending on tune. The thing is your car being a automatic and Ive only messed with 2 or the autos.
