Seeing that is a C2 race head, you cannot bolt a stock exhaust to it. There is no bracket supports, it will not yield the power and performance anyways, with the cyl and bottom end and head, not sure why you want to run it anyway, the pisser is easy on that head, just use the front exit fitting, or run a tee and split the water to run overboard then to the exhaust if you want to dry the pipe out. Dual cooling really can't be put on the stock mani , I mean you could but..then soo much water would be in that stock exhaust, making it worse than stock...just plug one of the pump fittings and go back to single cooling as org designed for that exhaust..my 002. Good luck.
