440/Schumacher/Borgeson

I should've went with the Schumachers.
Bought the ProParts semi-fenderwell headers figuring they were better and had more flow, but have had nothing but problems installing. It's been an absolute depressing nightmare.
You're lucky you made the right choice.

what issues are you having installing pro partd headers? i installed a few sets back in the day and they went in easily. even did a set with power steering. plugs were a ***** but they fit.
