The single valve I ordered arrived yesterday. I don't have the holding fixture for my lathe made yet, but the only difference I can measure (other than the head diameter) is the position of the keeper groove. The big block valve has a groove 1/4" from the top of the stem, while the stovebolt valve has a groove that's 3/4" from the top. A simple plunge cut the right depth with the proper shape and width of tool bit will duplicate the stovebolt valve. I'll be using these valves, along with the 1.6" diameter stainless small block V8 exhaust valves, on the 300+ cubic inch "261" that's on the drawing board. That's the one with the three side draft Harley Davidson carburetors. Jerry
