I can't comment on SB applications but on a BB tti's are the easiest header I've ever installed. I can drop them in 30-40 minutes and installation doesn't take any longer.

Two tips crap can their gaskets and also get arp small head header bolts. You will only need then on the 2nd header bolts on both banks(2nd bolt from the front on both sides).

I don't have a lift and install these while laying on my back easy peasey. I feel the 2" fits better around the starter than the step header.
