Tony, I think standard is 5/8in radius. Although I’ve used 2in radius on race engines, the wear rate is pretty unimpressive and I wouldn’t recommend on road cars. I’d go for standard and 1 1/4 in only. If anyone needs different there are people who will modify them. Worthwhile project though. I’ve just about run out.
