I had the opportunity to take a good look at the stock rocker arms today. Personally, I would be hesitant to change anything in the valvetrain that would place any increased stress on the rockers, ie: stiffer valve springs and larger/heavier valves. The stock cast iron rockers just aren't very beefy and look like they could break if subjected to any increase in stress over stock specs.. Does anyone else have a similar concern? I think lighter valves with near stock spec. springs would be a more reliable choice if you decide to run high lift cams. Just a thought anyway, as usual.
