Best Headers for a Big Block?
I need a new set of headers. Mine have one horked up collector, bent flanges and a lot of rust.
Anybody have good or bad experiences with any on a 402? Mine is BB, TH400, 2WD on a 3/4 ton. I'm interested in some ceramic coated ones, but I don't know where to start. Any mail order house suggestions with part numbers that you know to fit are very welcomed. I need to find some that fit without having to dent them. I also noticed my current ones are very close to the lower A-Arm bracket and would like to avoid that on the new ones. Thanks!

I have cheap dyno max headers(not ceramic coated) in my 71 LWB 2WD c-10 with 454 and TH350. went in EASY, didn't even pull the spark plugs, jack the front end up and put it on jack stands and they slide down and tip into place

I went with the Dynomax 86022 headers for my 402 BB.
They went in real easy and fit perfectly. Ed @ MotherTruckers hooked me up.

What about with AC? Do you use your original brackets? I'm thinking of headers but I want to keep my AC where it is

Thanks All!
It looks like I'll be ordering a pair from Ed. Luckily I don't have A/C any more, so I don't have to worry about that.
