the l&l's are a real nice header.the fenderwell headers eliminate some problems but the exhaust will have to dump in front of the rear tires unless you run it back under and then inside the frame ,then you could run tailpipes.the chassis exit headers are a little close to the front drive shaft.

the l&l's have nice thick flanges and are probably one of the highest quality headers you can get.the only problem is they are only 1 3/4" primary ,but if you are only running a 429 that should be ok.

you have to cut the inner fenders a little.when i had the l&l's thats all i had to do i think.i have hedmans now and had to clear on the drivers side frame/body mount.i don't thinkthe l&l's collector is that far back so shouldn't be a problem.

I am using L&L headers on my 79 F350 however it's not a 4X4. Mine are a chassis exit and I had no problems installing or running the exhaust. Their lifetime warranty is nice too.

it's the front drive shaft and the transfer case that get in the way with chassis exit headers.a 2wheeler won't have these issues.

depending on the amount of lift you have the driveshaft may or may not be an issue. The worst thing in my experience about the chassis exit headers is that the passenger side collector dumps right infront of the transmission crossmember, and this makes it kind of hard to route an exhaust pipe between the transmission and the passenger side frame rail, although this may only be an issue if you have 3" exhaust.

You shouldn;t have to do anything to get the fenderexit headers to fit IIRC, but I do know having a body lift makes it alot easier to get them installed but it is not necessary.

Also excellent quality on the L&L's as well.

Default I think they are money well spent

I have had 3 vehicles with headers. 2 Chevorlets and my 77 F-250 4X4. I have had nothing but headaches with the 2 chevy headers--loosening bolts, blowing gaskets, etc. but I haven't had a single problem from the L&L headers--still on the original gaskets after 3 years. I love them. I don't remember how much they were b/c I bought them with the whole swap kit (bought the kit b/c I wanted to keep the 4 speed with the 460) It has been in a 77 high boy that has hit its share of mudholes and they haven't failed me yet. I highly recommend them. I don't know much about cars (mostly maintenence items) but the header flanges on them must be 3/4 inch thick--I swear.

I bought the ones that exit inside the chassis and have had no problems with running exhaust. I have a divorced transfer case.

I love my L&L Products Ultra Flow headers. They fit great and the electroless nickel plating has a lifetime warranty. I've had them for eight years, on two vehicles and they look great (watch the footnotes).

actually a body lift gives you more room to work, but regardless there is no way I would want my exhaust that close to my transmission- it generates enough heat by itself...

I will second with Matt on that one, no reason to bring more heat into that area if not neccesary. I have the Heddman fenderwell headers on my bronco and I love them. They clear everything fine, just took about 1/4" off the front body mount to give a little more clearance. My dad had a '79 bronco with a 429, Hooker inside the frame headers, those things were crap. Even with a 4" lift it would rub on the front driveshaft once in a while, and with a rear sump pan, the drain plug was right on top of the collector, made oil changes a mess. Could never get that bronco to run cool either.
