Question ARP Head Bolts Part number

so I have the pre-2003 ls1. my z28 is 2001. I googled ls1tech on what would be the correct ARP part number but came up with various answers. the ARP site has 134-3609 however I also found this part number 134-3601 at a lower price but not listed on the ARP site? I cross-referenced the 134-3601 on summit as well as jegs and they appear to show the LS1 engine?

There isn't a single mention of the 134-3601 working for an LS1 on either the JEGS or Summit listings for them.

if you go to their site and click on the applications tab/section it'll filter to show that they are?
edit-unless this part number's for the LT1 93-97 but the site(s) just isn't updated correctly to reflect it?

Where do you see anything about an LS1 in any listing for 134-3601?
Even if you filter out the years and it shows up as 99-01 Camaro, it still says it fits a 350.
Not to mention, even a glance at the picture shows the wrong number/size of bolts.

You need the 134-3609. Bought a set 6 weeks back. Was very hard to find, but I understand they have started producing them again.
