I did a search and couldn't find it. I just need to know what size tap I need to use to clean the threads in my GSR block before I put the ARP's in. I've heard 11x1.5 and I've heard 12x1.5. If it's 11x1.5 I'm screwed because I can't find that anywhere. Please help. Thanks!

 

Just measure the thread pitch of the Stud?

Or....call ARP Technical Support: 800.826.3045 or 805.339.2200

Yeah I called ARP and a chick said it was 11mm by 1.5. But I find it hard to believe that it's an 11mm. And I can find an 11mm tap anywhere.

 

It's M11x1.5. You can get a tap from Sears in the metric tap set.

Use an assortment of a 1/4" extension, 1/4" drive 10mm socket, M6x1.00 bolt, and M6x1.00 nut to create an extension to thread the tap down into the block if you don't have tap wrench that is long enough.
