A couple of tips for using exhaust manifold clamps

What ARP bolt #? I see several.

At the time, I went with ICT billet for manifolds and oil pan but ARP for the head bolts. I already have a set of ARP oil pan to go in and considering manifold bolts, too.

This was one of my questions, too, since my day will come. All I see are "header" bolts for mine -- I could be blind. Is this one size fits all? What part number is everyone using for stock manifolds?

ARP 134-1102

This is what I used also^^^^^ 134-1102.
There a few that will fit depending on what finish- like chrome moly or black, bolt head 12pt or 6 pt or if you want studs with nuts. These are the black 6-pt bolts.

I think that’s what I narrowed it down to. I was also confused by the 1/4” or 3/8”. Is that the flange thickness or the bolt head?

I don’t remember. ARP’s website says 3/8” flange but I don’t think I ever figured what that meant. They looked like the heads and flanges were what I wanted.

Kind of surprised they come with washers; I didn't think washers were generally used with flange bolts.

I need to add this to the to do list for mine. Anyone have a link for the bolts?

Oops sorry missed the new posts.

Here’s a couple pics. The washers are real thick, maybe twice as thick as a regular washer. They’re also a bit bigger in diameter than the flanges on the bolt. All in all they’re a great product imo, like every single ARP product I’ve bought. I like the fact they seem like the clamping pressure would be good.
