Nothing too good for my LS1 lol I just spent $65 for 12 header bolts. That's more than $5 per bolt. 
I got the Breslin Performance Products Split-Lock Header Bolts. What can I say, I'm into cool fasteners. No need for locktite with these babies.

...I remember a good sized thread on this topic and I thought most of us were using the blue locktite. No?

I was talking about those with a buddy of mine and he thinks that they aren't very good for the threads. He's probably the most mechanically knowledgable person I've met, so I'm going to pass on those and probably get the ones with the triangular washers that rest on the tubes to prevent rotation.

BTW, I thought you'd found a 12-bolt axle for $65.

...I edited it so there's less confusion lol.ARP makes studs but it's no fun getting the headers PAST them on the way up.

However, the GM service manual does indeed recommend the use of locking compound on the header bolts. It's actually GM P/N 12345493 , which is equivalent to the permanant red Loctite product.
From the manual:
1. Apply a 5mm wide band of threadlock GM P/N 12345493 or equivalent to the threads of the exhaust manifold bolts.
In the end the most important thing is to avoid cross threading the bolts, which is easy to do if you aren't careful lol.
IMO if you elect to not use a locking compound or a locking fastener, it would be wise to check them for tightness from time to time. Because when a bolt(s) backs out, that is when you could do damage to the head.
FWIW, currently I have stock bolts with blue Loctite on the driver's side and Breslin locking bolts with antisieze on the passenger side. I'll leave it that way for a while and see what happens lol.
Let the bludgening resume.
