Going to be putting a PI engine in my 98

Found a low miles 99 GT PI engine that im going to pick up. It has the 8 bolt flywheel on it. I want to figure out some parts to put on it to help out the power and everything

Aluminum flywheel (fidanza)
King Cobra clutch
Comp Cams valve springs
Longtube headers (what brand.... thinking hooker, but kind of $$$)
Matching O/R X pipe

That would probably be all I put on it when I install it, because that will be cleaning out my bank lol. I already have the valve springs, so want to install them. I have an alum flywheel on my NPI motor but i have the 6 bolt crank, so I need to buy a new one in order to use it. Do you think thats a good idea for me? I liked it on my NPI motor. Let me know

Please tell me what to buy and WHERE to buy it for cheapest please

Well I would install the valve springs now so i dont have to install the new springs IN THE CAR. I already have the springs, i know they wont make any difference in the power of it all. I know other guys have some input..... c'mon TTT
