        Will these fit on an engine with GT40P heads? Really want a good set of headers that will fit but don't want to spend a bunch of money. Thanks

        • The BBK 1-5/8 in. Chrome Unequal Length Shorty Headers are designed for standard layout heads, and will not work with GT40p heads due to their revised plug angle. At this time the MAC 1-5/8 in. Ceramic Unequal Length Shorty Headers for GT-40P Heads are the only shorty headers we offer that are compatible with the GT40p heads. These are linked below: https://www.americanmuscle.com/mac-ceramic-unequal-shorty-7993-gt40p.html

        How much hp will increase?

        • Power gains with the BBK 1-5/8 in. Chrome Unequal Length Shorty Headers will depend on what other mods have been done, but on average you will see around 10-15hp.

        Whats the difference on shorty, equal an equal headers will they all fit 302 with out doing any modifications? Is there a difference inHP?

        • The difference has to do with the primary tubes. For more information on the different headers, check out our article "What are the Best Mustang Headers?":https://www.americanmuscle.com/best-ford-mustang-headers.html

        I have a 1991 Ford F-150 with the 5.0 302 will they work on mine

        • Unfortunately we cannot provide fitment specifications for anything the product is not advertised for. What I can say is even if it may have similar/the same specs as the respective Mustang these headers are advertised for, it doesn't necessarily mean it will bolt right up.

            BBK Header

            Great product. Install was fairly easy. The sound is second to none,especially if your running a big cam. Fitment was kinda rough do to the fact that the steering shaft touches and the dipstick bracket isn't exactly where it should be. I'm still trying to work these issues out. Awesome header for the money and thanx again AM for another great upgrade!!!!!

            Very pleased with price and sound, I removed my smog system and h-pipe and replaced with xpipe, so these puppies were a cinch to install, fit right in and got no leaks first shot, they discolor quickly as expected and you will have to modify your oil dipstick.

            BBK unequal shorty headers

            These shorty headers were a great easy add-on to my fox body. Took only 10-15 mins to install them they look great and I can tell the exhaust flow is much better than my old stock headers.

            As a do it yourself kind of guy and my only other experience doing headers was on my 79 f150. These headers were a breeze. If you can read and turn a wrench you can install these headers.

            super beast!!!!!!

            These headers are an OE approved piece of hardware!!!!. these are probably in the top five best things I've bought from AM other than my e303. these headers compliment my cam along with my exhaust system. I literally had no idea these were chrome (super shiny) lol. other than the sound the chrome finish catches a lot of eyes when my hood is open. Another satisfied customer AM. keep up the awesome work!!!

            Great headers for the money

            Easy to install as long as you have a torch for the stock header to h pipe bolts. Sounds great can notice a little more power. Came with all gaskets and new bolts / studs Headers Starting to change colors now after about a week of driving.

            not bad

            They were an ease to install. Only thing the bolts they send with them are too short so I had to use the oe bolts. And have noticed already they are starting to turn color.. no big deal I didnt put them on for looks anyway. As far as performance I think they may have helped a smidge. But they definately helped with the throaty sound I wanted!!
