 I personally don't like the rotating header flange, they tend to push out and split the gasket as there is quite a bulge where the flared sealing flange is, problem gets worse as the street hook up has the same deal. 
I have Tig welded the flange both sides before and then ground and Roloxed off the flared bulge. I also noticed the quality of the bends and port flanges etc got worse when they changed to Blackjack name. JMO.
I put many different make headers on the 67-69 Camaros and Appliance was the only 1 that did not have any clearance issues with steering box/pitman arm or frame fuel line. etc. Wish they still were available.
