302 headers
I was wondering if it would be worth my time and money to put a set of factory headers off of a 302 H.O. out of a Mustang on my 93 Pickup MY factory Manifold has cracked and I found a good deal on them but I am not sure of the exhaust work I have to have done to bolt them up and if the gain would be worth it any help would be appreciated Thanx

302 headers
The Mustang headers do not line up with the factory exhaust especially on the driver side. However you can have an exhaust shop manufacture a new piece for your y pipe on the driver side and enlarge and flare the passenger side. I had that done when my truck was still 302.

Yeah ,
I called my exhaust shop and I can get the headers and hooked up to the pipes for about $80 or I can spend $75 on 1 stock replacement I was wondering if it would be worth the extra to do the headers or if it would just be a big headache thanks

302 headers
I never drove the truck before hand with the manifolds so I have no comparisons. It definitely can't hurt though. The headers fit in just fine but the flange on the passenger side makes it a little tricky to pull the starter bolts if you happen to be laying in a parking lot as I once was.

And BTW, I think my exhaust shop quoted me $100 Cdn. for modifications vs. $120 Cdn. for new manifold. Yes, it was worth it, especially since I got my headers for free. If your truck doesn't have a front fuel tank, try seeing if the Mustang H-pipe will fit in too for full dual exhaust.

302 headers
Pick up a set of summit racing's shorty truck headers for $160 and be done with it. No head pipe modifications necessary! I know I bought a set 2 years ago, and have yet to have 1 major problem. (small problems do exist though, header to head gaskets burned out).
Trust me, it's alot easier to buy something that fits right, than to just make it fit, and have to pay the price later.
1988 F-150, SWB, 5.0 EFI (formerly 4.9 EFI), M5OD 5 speed, 3.08 gears, Summit shorty truck headers, Custom built Flowmaster exhaust system. Force 4 LP6000 lightbar, Federal signal PA-300 100 watt siren, Icom IC-V100 50 watt mobile radio.
=======================================
1965 F-100 (just purchased 1/18/01), SWB, 390, C-6 auto. Dual exhaust, Not much else to do to it.
Can see both below.

302 headers
I had the same problem with my 88 F250 5.0. I went the mustang route with shorty headders. My whole exhaust system needed replaced so it didn't cost any more. As for power difference I went from a stock system to headders, 2.5" duals, and flowmasters and I noticed an incredible difference, along with an extra 1.5 to 2 MPG!
Also beware that long tube headders will not fit correctly! And they cause a REAL bad angle for free flowing exhaust!

I have stock manifolds on my '90 F-150 but i thought about putting headers on it. Also i have a '93 Stang 5.0 with factory headers. These things are tiny, i think the manifolds on my F-150 has more flow than the headers on the stang
