Where to purchase big block exhaust manifold bolts

[Joe R.]

I did a brief search in the archives, without any luck. My L72 (427 / 425) exhaust manifold bolts are shot. The head markings are rusted off of them for all practical purposes. Where should I get a new set?

Thanks!
Joe

Joe,
I'd be interested to see what the special thick washers looked like, do you still have those?

Joe,

someone a while back mentioned AMK, I ordered exhaust manifold bolts from them for my 68 and they are darn close, integrated flange, with tri-lobe thread design that is self locking and as close to correct head marking as one would expect. Their web site is not the easiest to navigate, but the catalog is great, you can cross refference by GM part number from your AIM.

Good luck

Ron,

I have washers on some of the exhaust bolts. I can't say that they are or aren't original. I'll take a picture for you. Do you need dimensions, too?
