the water doesnt come in untill obout 2 inches out from the flange on the headers and thats where we put them to me a lot easer just drill and weld but thats up to you and as far as good reading on the dyno we put them in the header 2 inches from the flange just my 3 cents

When my 500efis were stock, it would run between 1450-1550on pump gas. I was told that pump gas [93]will running higher than race gas.My Chevelle runs up to 1600 on the hwy holding it steady at 4500 to 4800.its only doing 65 at 4800rpm,on the nitrous it cools off,Now with the whipples in the Hustler it never gets above 1300, Precision Marine's dyno doing steady state pulls it would level out in the upper 1300's ,went up to 11.5 lbs of boost the temps went down, I guess the fuel map goes richer in the upper boost ranges.Rob
