so it sounds like most are suggesting the eddy rpm heads.The fact that i don't have to buy after market valley pan,intake and headers is appealing.The only thing i've read is that the valve seating/alignment is off along with rockers....not sure

i am considering the TTI headers though.

600hp would be my max since i don't plan on sittin at the track all the time,i like to cruise.Pump gas is a must since the $$$$$ for it is already crazy.

Since my diff(742 case) is stock and i think the trans(both rebuilt) what would i have to upgrade on these to handle 550-600hp?

i'm running street tires so real hard hook ups probably won't happen.
