    That kit linked off ebay. best price I've seen.
    and my cousin just did it and stated that it came with every bolt, and gasket you need. that's good.

    You'll want a helper for a few parts of it.
    Getting the new head on with the dipstick tube through the hedder is a PITA.
    Also you should zip tie some of the hedder bolts that are right next to the strut tower.
    there's not enough clearance to get them in once the head is on.
    put them into the head, and tie them together so they stay in but don't go all the way through.

    buckets and floor dry are good because you'll loose fluid pulling the head.

    I'd also recommend plenty of cold drinks.
    good luck

    I think you're referring to Ryan98GT (aka 98Saleen). He went with Fox Lake Heads and aftermarket cams.

    I only gained about 40rwhp w/ the Headswap. The only thing I did different was to lower the C/R slightly, but that wouldn't make for a 70rwhp difference. Nothing else was changed at the time. Same tuner, same dyno.

    In other words you won't get 110rwhp (~130BHP) from the headswap only on a blown setup.

    I dont think that's the same guy.
    I asked him specifically about it. He said he was running as much boost as he could on his NPI's.
    He said 100 HP, but I have no proof. It could be inflated.

    I looked through my Corral PM's, but couldnt find it.
    That was years ago.
    You could be right, I'd have to do some research.

    I'd definately do a cam, they're more efficient than the stockers.



    97 - What do you mean, you say you have PI heads, but don't know if you should keep the NPI heads?
    Do you have the heads or not? :)
    I'd recommend a cam, there's a number of good grinds out there.

    I just bought some brand new PI heads and cams but I dont know if I should just keep the NPI heads that are on the motor and just do a custom cam swap or since i got the heads should I just go ahead and swap them out. I am planning on runnin a procharger down the road so Im trying to build up what i got now. Theres too much back and forth for my little brain to concieve

    If you already have the PI heads and cams then use them. The PI heads will give you a better selection of cams later down the road.

    True that, you'll also get more top end, especially with the Procharger.

    If your staying NA then the stock 19lb injectors are fine...they are good for over 300rwhp NA.

    i read about all the neccessary parts for the PI intake swap, what website were all those parts numbers from? And another thing, i want to do the whole swap so what kind of accessories would i need to make the PI heads also fit? I was looking at the FRPP head changing kit with all the gaskets and bolts but wasn't sure if that would get me all the stuff i needed, plus the stuff you mentioned for the intake swap.

    If you do a headswap kit, it comes with the intake and all the bolts and gaskets you'll need.

    All right.
    you'll want a head changing kit which has new head bolts.
    I'd also get new intake manifold gaskets, and front cover gaskets.
    RTV silicone.

    Think that's it.
    Good luck, you'll like the results.
