I have a 94 gt with 130k miles on it. Want to upgrade to gt40, gt40p heads and intake. Not sure if I want to swap the cam as well and tune it or just leave the stock cam in it. I have 2 options off craigslist for gt40p heads. First is a set that came of a running foxbody. He bought the car with them on it and isn't sure if the valve springs have been upgraded or not but they come with 1.7 crane roller rockers and said they ran on an e cam with no problem and they are $300 for the headers and roller rockers. Second option is a set that has been upgraded with trick flow springs and had the deck resurfaced 10k miles ago and don't come with anything else but the heads for $350. Neither state anything about a valve job or anything else other than what I stated here. I heard that that if you run a cam other than stock that the 1.6 rr are good but stock cam can run 1.7 rr for a little extra lift but may have ptv issues. Are any othe these a good option or should I just find some stock ones and do the work myself, and by myself I mean machine shop. I can buy a n set of aluminum heads from lmr for $900 so I don't want to be too deep into gt40 heads. I know the aluminum heads are the way to go but budget wise right now aren't an option. I'm just wanting a little more punch out of my stock motor until I get around to building another one. Btw, my motor right now has the typical bolt ons. Headers, off road X pipe, flow master dumps, Cai, 70 mm throttle body, and a msd tune up. My headers are the bbk shorties and I'm already running 90 degree plug wires so I shouldn't have issues running gt40p heads according to what I've read. So so what are your thoughts on this? I'm not looking for the "300hp to the wheels" like many others are from this setup, but just a bump to keep me happy. You know us, can't ever leave these cars alone.
