best thing to maek sure they seal/install properly, is to cut 2-3 cleaning groves across the threads of an old head bolt and run it through each hole to clean the OEM bolt crud out....
Or use a tap.
tap cuts out the root of the threads and weakens em.
use a thread chaser or its cheaper to cut slots in the bolt with a 3" cutoff wheel or a dremel...
How straight would the slots have to be
not at all, but i cut em at an angle, one in a clockwise and one counterclockwise..one cleans well going in, the other cleans well coming out...then just a wire/nylon barrel brush "thread" em and/or compressed air
Hmmmmmm... Just want to clarify the torque spec and ask what everyone else has done.
For the L67, 3800 block, head STUD kit, ARP says 80ft.lb with Molly Lube (link)

I've read, 75, 80, & 90 ft.lbs respectively online... What say you?
this is what I used to seal the threads: http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
as far as the torque sequence, I dont remember if I torqued them incrementally, but I do remember I torqued them to 80 ft/lbs. been driving around for a couple weeks and no issues.
