Advice wanted: Low buck rocker options

There's really no appreciable benefit on any engine from roller rockers regarding power. It's arguable at best. What's not arguable is the friction loss at the valve stem and the valve guide. Without the rocker scrubbing across the top of the stem, valve stem and guide wear are reduced significantly. Those are benefits you cannot ignore. If 1000 bucks is your threshold, you have lots of choices. I would go with the Comps.
