Here's the part #'s: # are 11589154 on the studs, and 11609746 on the nuts

-Thanks to Supersub for the revised numbers
-Original idea was by EVILGMC, so thanks to him for bringing this to our attention.

Note: the studs come in packs of 5, and the nuts in packs of 4

 

thats pretty sweet should make it alot easier to get them on

 

Of course. Who would want to make it easy?

 

I figured it would be the other way around... usually you wont drop the stud so i dunno why they come in a pack of 5..

 

They just took 2 studs out of a bag for me....so it was 2 bags + 2. No biggie. They're made for a 3.4 v6

 

it has to make things so much easier. i will be getting these forsure.

what was the grand total if you dont mind me asking?

 

$42 I believe

 

Any idea what the thread and length are on those studs?

 

FWIW, ARP makes header studs for LS1's as well, P/N 434-1301 , but they look to be about $100 for a full set.

 

GM's are less than half the price, and are better. The nut locks in place much better and stays tight. I was looking for an alternative to the ridiculous priced ARP's and came with these GM's. You should be able to get them from Gmpartsdirect for a really good price.
