mdross1,
Can't help wondering about solid rollers, bushed or needled. From what I can glean on the 'net (yeah, I know how reliable that can be) it seems idling is the solid roller killer, especially if the lift profile is aggressive from the start.
There are cams that have "softer" initial ramps, and cams that use tighter clearances that may help. Spending some phone money talking directly to Isky might save you some pain...
Most of the solid rollers I'm aware of are maintenance items; you run them 3000-5000 miles and then have them rebuilt. If you have low total miles to run the car it would seem more like a practical choice.
My hydraulic BBF rollers have gone 30K+ miles without the valve covers off. I do agree mine probably sounds tamer than a solid roller would
