I have an 1982 f250 with a 351w I took the stock manifolds off and I purchased summit racing long tube headers for a mustang 5.0. I know that they will bolt up to the heads and I also know they will clear the body because my truck has an 3 in body lift along with a 3 in suspension lift. MY question will I have any problems with the big bulky cross member that runs under the motor/ or what ever that piece is called lol. The way the headers look I think it will be close with that beam being right there. The part number for the headers is sum-89030

 

Well, there's only one way to find out for sure.

If not, I have a pair of unused Hooker headers for an 81-86 F250 w/ 351W in my shed I'd be happy to part with.

 

Great I am actually about head out to the shop right now and see if they will I will let you know
