i have always believed that you should go to a solid roller too, but sometimes because of application or user inexperience, it's not always doable.I have a great customer that i wouldn't trust to get the valve cover off,let alone adjust the valves or even know what he was looking at. He likes power though and doesn't want problems, so hyd. rollers are usually what he ends up with.While the ramps are designed not to have lash, i haven't yet seen where .004 (the most i've ever ran) has had any effect on life of parts. It does make them a little noisy though.
Have you tried modifying a rev kit for it?I've used the AFR ones on the small blocks and they work really well. I did a BB Chev for my dad's suburban with a hyd. roller and toyed with the idea, but ran out of time to apply it. I don't think it would take too much work to get it on there and would really help those heavy valves over 5500 rpm.
