Hey Landman, I have been looking at a bunch or arms due to a failure on my engine. And from what i have seen two seem to stand out, the Harland Sharp and the bushed Rockers from RAS.The Sharps have approx twice the area of Crane gold arms, my builder loves them. The RAS arms look very strong and are bushed stainless steel, look of good said about them. The Indy,Hughes and Dove rockers are said to be the same just repackaged, they have some bad press about them, check for your self. The Blue mopar Performance arms are said to be the same as Crane gold units. I have used the Comp Cams Arms and had good luck with a solid flat tappet cam, however a failure on a solid roller application, my fault. I have a friend using the 1.6 bushed S.S. 440 source arms in in a roller 512 with good luck. Let us know a bit more about your application, cam type, spring pressure and application and we may have more info to give. Good Luck
