I found a set of Mustang Foxbody headers for a deacent price. I am told the bolt holes in mine are way too "wallered out" Will these fit my truck. 1993 F150 5.0? These are for a foxbody mustang 5.0

 

What brand are they and are they shortys or longtubes? Shortys will but wont go lower than frame rails

 

Headman and they are shory's I currently have shorties but I am told my bolt holes are too "wallered out" causing them to leak. I doubt it but if I can get some new ones that would be nice.

 

I am a fan of the longtubes , they make more power. But thats just me. Any i would think if you use good gaskets on your headers it should not leak.

 

I like the old white Mr gasket header gaskets, with a thin layer of permatex ultra copper silicone smeared on both sides, I had a set in my Duster for at least five years, and they looked good enough to re use when I took it apart to swap heads. I can't see why you couldn't fix a wallered out hole, (that's wallowed in canadian, sloughed in nova scotian) weld them up, drill em out, or get washers and file them to fit around the tubes, or buy some cheap mustang headers.

 

I'm not talking header to block header to. Exhaust end. It isn't lined up right. Took it to one shop he didn't want to work on it when he saw the bolt holes he's probably the only one in town who will work on a gutted cat system.

 

red RTV and sandwich the gaskets... it wont leak...

 

No gakets just a 1/8 sphere below the header that goes into a flanged out exhaust pipe. To make matters worse I have now rounded off 1 of the 2 nuts that holds said pipe up to it.

 

You need to take some pictures.
