I am guessing this is your first solid roller engine based on your original question? Gsharapa has a lot of experience with solid rollers u don't (not insulting U).
You do need to keep a keen eye on the lifers for changes in lash (I would never go that long without checking lash and i run oversized 904 needle free lifters and lifter bore sleeves (SBF) . Valve Adjustment my not be needed, however; an inspection is needed. You implied only 2000 miles a year, but that will be stop and go and a lot of heat cycles). Sitting in traffic low idle is a killer on solid lifters. U get the picture.
R u willing to pull the lifters out of the engine after 5000(give or take) miles and check them or have them checked? Will u inspect lash like should?
Buy what U want, but make sure the extra HP is really something u desire. It is going to cost u more money, and will require more attention on your part to run a solid roller engine.
Best of luck on your decision.

The support engineer at Isky told me that with their EZ Roller lifters (bushings, not needle bearings) I need to check the lash from time to time but if that lash is not changing then the rollers don't need to be removed and inspected. He also mentioned that typical solid roller lifters need to be inspected and possibly rebuilt every 7,500-10,000 miles, but the Isky ones should last probably 3-5x that long if driven on the street. I suppose he could've given me incorrect information, but he seemed to be on top of things, and is an Isky support engineer (also mentioned he has these in his daily driver). Am I naive to believe him?
