I am going to be pulling my headers to do some maintenance. I want to change the bolts to Allen heads for better clearance and was wondering if there is something special about header bolts or can I just get some grade 8 or stainless 3/8-16 bolts from a hardware store and call it good?.

ARP sells some really nice 12 point Stainless header bolts, that's what I run.....and NO RUST! The 3/8" 12 point heads make wrench clearance do-able on all but the tightest header tubes.

Rob I use the allen head stainless. I don't have any 12 point sockets or wrenches.

for some reason my 460 likes to loosen up the exhaust bolts. I went with the percy's stainless ones, they have a small allen set screw in the middle of them, you set, once re-torqued, have never loosened up since.

Yup, those are about the most fool proof way to deal with problematic bolts and nuts. ;) I've seen pics of people running braces from the collecters on thier OT headers down to the bell housing too......

My headers came with 12 point bolts but the flange at the base of the bolt head would hit on a couple header tubes and wouldn't line up. I replaced those with allen heads to get through last summer but now its time to make them all allens. Less tools to carry :)

:like:Well thanks Steve, now I have a 12 point wrench and socket!!!! Just ordered a set of the Percy's. Need a way to tighten them,$5 bucks a piece but I think they will be well worth it!

I prefer studs...and I use brass nuts. I have aluminum heads....and am always worried about cross threading....or stripping em. Not that installing headers is hard....but studs make most things easier/quicker. To each his own I guess.

Yeah, I left them out on purpose!!! Didn't want to take it to far to the "R" rating!!!

Studs do make a sound fastening solution, as long as you have enough room around the nut, to get a wrench on it. :)
