Wanting to some work this winter... Need Help!?!

[Buck_Nasty_Pony]

Ok I am plan on doing some work to my 98 GT this winter and I have a few possibilities in mind. I was pretty dead set on porting my NPI heads and putting cams, springs, valves etc. Because I was told that you could run bigger valves in the NPI heads. But the more I read on it seems like it is fairly easy to buy some PI heads throw a cam in it and get close to 300 h.

Just wanted to get everyones opinion on the subject, things I would like to know is which would be cheaper and which one is going to be easier?

Everyones opinion is greatly appreciated!!!!

To me it's just as easy & cost effective to do the complete PI swap. Although a little more expensive.

Seem like we in the same boat.....Im stuck on porting my NPi heads to even the Custom Cams i got are for PI heads i still think they fit NPi heads but the NPi route would probably be cheaper considering you would have to buy some PI heads but the PI route would probably give more horsepower because of the Compression Jump........

I've got a set of pi heads and an intake for sale if your interested in doing the swap. I'll make you a better deal than your going to find. pm me if interested.
