    sorry bout the insult. you guys are right i could have listed the website. and i thought you were implying that i didn't search. my fault. im not up on my forum ettiquette. anyway i agree it would be nice if they refunded you when they tell you something will fit and it doesn't and i know about the firewall issues. they have another set for early falcons which i thought might be better the ff6 but not made for gt40p. ill check out the crites site thanks.

    Crites are the only ones, unless you want to do something custom....

    Jesse (a mav owner on forums), in spokane said he flipped his headers upside down and had them coming up then down & back to side rear wheels.

    Personally, I would have taken his posts (actually I did) the same way you did. They came across to me as a bit snotty, could have been worded differently. Things can be taken way wrong when you aren't face to face.

    I would like to see pics of those upside down headers. Of course, if I had mine mounted upside down, I would also mount them backwards and put a hairdryer or two on them.

    Or straight up out the top of the hood, with a glasspack on them??? That would be pretty cool. Anybody ever see anything like that?

    Saw a car at a cruise-in last summer (think it was a SBC) with two carbs, a carb supplying each head through the head's exhaust ports and headers sticking straight up from the head's intake ports. Required a special grind cam and obviously it's now breathing through small exhaust valves, but it was different looking.

    Sounds like an awful lot of work, to be different. :90:

    A header trick that works on everything but I never tested on a Maverick was to take the stock Explorer steel manifolds and cut all of the tubes off leaving only the side that goes to the block. then grind them smooth and use them as spacers to move out the headers about a 1/2" which is just enough the keep the plug wires from burning off. Order 2 sets of exhaust gaskets for a 91 T-bird with a 5.0 and you will never get a blow out and buy allen head screws from Home-Depot that are about 1 1/2" long to install them to the block.

    I'm thinking of taking a set and having them angle milled to see what happens as far as clearance.

    I did that, put a multi-layer gasket between all surfaces for another 1/8" clearance, used $16 EACH shortie Accel spark plugs, and took a plug socket and cut 1/3 of the wall away so I could slide it on at an angle. I also had to drill the socket out so the plug tip would fit through it, and shortenend it just enough to reach the threads, then used an open ended wrench to remove the plugs.

    Still was just easier to pull the header all the way off, or at least jack up the engine, drop the exhaust on that side, and drop all header bolts but the front one so I could swing it out of the way.

    After 2 years of that, I went back to GT40 non-P heads.

    I would never want to do that again.

    Before and after images of the plug socket...
