Lippy how will u know if the lash has changed if u only check them ever so often? The bushing lifters will give u more warning then neddle lifters of pending failure (big plus) and they handle load better . That is right about the lash (not changing). If the lash is not changing, or if it is changing by a very small amount, and the lash between each lifter is close, u are in good shape. But u need to keep an eye on it. If the lash starts changing on one lifter more then the others then u have a problem. The bushing lifters will last longer and will take more abuse, but personally i would feel uncomfortable not pulling and checking them by 7500 maybe 10000 even with a very mild cam. I still want to see over all condition of the lifter. Maybe i am too conservative.

I could see making 30000 miles, if U do not rev the engine high, your cam is very mild, but then why would u want a solid roller???

I am not an FE guy so maybe some of the guys with solid roller FEs will give more guidance on how often they check lash and pull and inspect lifters.
