Some time ago, Gary and the boys at Rocker Arm Specialist (now known as Rocker Arms Unlimited), offered some pretty nice stainless roller tip rockers but due to production/getting materials and other 'reasons' they haven't been offered, but they're back!! Gary told me they're available in 1.6 ratio only. The earlier batches were investment cast but the current ones are now CNC machined. I got my set this afternoon and although I haven't done an analytical on them, they look pretty good! If you're interested, drop them an email or give them a call.
