Dang, get up in the morning and the entire thread is shorter. You know JD, we've known each other for many years and what happens under my cover will remain a mystery too, despite what is said on this forum. There's so much more to building an engine than this, it's in the process of building, the details, that's the devil of it. I have a set of Jesel Sportsman rockers here and was thinking of emulating their general shape out of 7075 T6 along with their bearings and roller tips. I have a good friend who is an engineer at Boca here in CT and he's in on this. At least his mill is DRO equipped. The Jesel's are apx. .895 wide and because of the extra length involved 1" seems a better way to go. I can see why the Arias rockers would be .275 around the bearing area at the bottom. With a length of apx 4" from the pushrod to the valve contact point there's a lot of stress. I don't have a set of stock rockers. Head, block and crank was all I picked up, figuring I'd have to build or buy all the rest anyway.
