Get the rockers, recommended though to get Oil-restricted pushrods and 105 springs so there'* no valve float in the higher RPM'*.

Just by looking off the stock gauge I'm at 8.5-9.5 used to just peg 10 before off 3.4
My TOG'* are going in in 8 days and a 3.2 will be coming with it. Should be back up to 10-11ish hopefully with no KR.

I was not concerned with losing POWER AT ALL. I know that I will lose boost ( power ) when adding the rockers...and that the Rockers will give me 25+ HP gain. I am wondering if the Boost Loss from adding the Rockers and the Rockers HP gain will cancel each other out. I hope that I am making sense here....

You're thinking (if I understand correctly) that you'll gain from rockers, and lose a little from boost? That'* not the case. You'll gain from rockers and lose indicated boost, but still have the same flow.

all I know is when I add a 3.4 from the stock 3.8 I get about 25hp gain...boost rises about 3psi....and if Rockers decrease the boost PSI...Logic would assume that the HP is lost as well.

Adding headers will also lower boost because of increased flow, than smaller pulley to bring boost back up again. Me I have 3.4 now with rockers, headers going on next weekend, will see how much more PSI is lost. Take it to my buddy with Atap, go for a run and than slap on a 3.2 and atap again, I'm confident all should be good.
