Just bought some complete pi heads. I already have the PI intake manifold installed. What kind of gains am i looking at. I know it raises compression so i will be making more than a 99+ GT stock but how much? 15rwhp more maybe? My goal is to get 300rwhp with the PI Complete swap and my current mods.

i thought i heard it will give you about 70 hp...but maybe i am wrong...

finish your exhaust and get some cams and you'll be close

your gonna need cams and LT's to even approach 300rwhp but you have an auto and that zaps even more power so 300rwhp is harder to get.
