3400 Headers (2004 Monte)

[whitelightnin04MC]

I got a set of S&S headers recently off of someone on an Impala forum. What can I use for the front studs. Specifically, I'm looking for bolt size. Would those locking header bolts work? The kind with the retaining ring.

Thanks for the help. Any tips would be nice too!

Pretty sure he ordered them from Summit...

Much appreciated

Just to be sure before I order these. I want the 8mm - 1.25 x 25mm ones right?
The ones for the LS1/LS6 and not the gm v6 ones. The gm v6 ones are 3/8 x 1 inch.

Correct. I'd just order the one's in Todd's picture: PN 608-026

Thanks again. My pn will be a little different since I want the black ones, but I'll be sure to get the ones with the same size bolt, length, and pitch.

Ok, so after attempting to contact Breslin to buy these headerbolts, I've come to the conclusion that they aren't in business anymore. So here's a new question.

The ones this guy used are 8mm x 1.25 x 25mm long. They are the same ones for the LS1/LS6. If I reference those motors for header fasteners from a different company, the fasteners are 8mm x 1.25 x 22mm. Will this be a problem? I'm really trying to get all this crap together. I need a few things from S&S and they're not open on Fridays so I have to wait til monday to order.
Here's the link to the set that I'm looking at on Summit:

I just used the same stage 8 bolts on my header install, so yes they will work.

Thanks man. Gotta love these message boards. Installation slated for April 7th.
