The R3 flange face is recessed into the head which is why alot of headers I've seen use the stock flange.
It might not help the guys OS but I could see the guy where I made mine and get some pricing etc.
He is keen to do more......... he has advertised in some local magazines to do custom R3 pipes.
Here is a couple of pic's of what I have ended up with......... I'm very happy with them, don't need heat shields and on the dyno with the 3 muffler setup is comparable to the other popular Aussie brand.
Your headers are beautiful Les .. the only thing that stopped me getting your mate to make us up the 20 sets was the quote/cost for the flanges..... To me the fact they don't require heat shields is an enormous plus .. I've been quoted nearly the price of the headers to have heat shields added.

Bloke that was going to make our headers was confident the flanges could be stamped out with the right size press. Reckons he could get them laser cut out at Strathpine for $5 each , but need to get 100 sets (that's 300 flanges) done at the absolute minimum. Lot different to the cost of laser cutting though.
