I know it's been several posts since this went by but do not use the fiber timing gear. Use an aluminum one. Fiber ones will shred suddenly leaving you stranded. In the process it will take out a cam lobe or two costing you a cam.
Speaking of cams, there are steel ones used on early engines and cast iron used later on. You must use lifters compatible with the cam you have and I don't mean just solid or hydraulic. The material must be compatible. Plus if you use a cam with a taper ground on the lobes the lifters must be radiused to match. Hopefully the cam grinder will tell you. Dave Crower offered to do this for free if I sent him the lifters but I developed a way to do it myself. I had bought the custom grind cam from him. Just so you know. I have been told this isn't an issue on our Stovebolts as the lifter bores are off-center to the cam lobes so tapered lobes aren't necessary. You should check on this issue. It could save you a bunch of grief.
