Default to O-ring or not?

Just wondering what you FI guys were going with. I'll be putting Noyzee's twin setup on my car here shortly, and I'm working on getting everything setup for it. So is everyone running O-rings or not, and what gaskets people are running (stock graphite 6.0 gasket, etc.)?

My o-ringed block (408) with reciever grooves in the heads leaked internally with copper gaskets but seems to be holding up with stock 6.0's. I was told o-ringing was not necessary until you approach 1000hp. Food for thought.

GM MLS 6.0 head gaskets

No o-rings.
