Re: 71 4x4 BBC Swap: Doing what I should have done the first time!

My two cents on the headers. You need to find a set that hugs the block. Looking at the picture for the 2817HKR and I don't think they will fit. The tubes looks like they are stacked on top of each other. While the 2455HKR only have one tube that crosses once on the driver side. Guess what that one tube that is stacked is the one that is hitting the frame and I have to bend in towards the block. The design that has them all side by side is what you should look for in headers. What heads do you have? Do have had a round or square exhaust port. Just another detail to look at when buying headers.
