248/254 duration @0.05 with ~ 0.575 lift isn't small cam in an LA and for the OP, it's agreeable that it would be too big, but no one is advocating for a cam like that.
The trend in a daily is always hyd lifters, whether roller or flat, and I would no longer build a flat tappet engine.
In yesteryear, many, MANY cars came with solid lifters or OHC like the mercedes diesels. They typically needed adjustment every 10k miles. NOt really sa big deal. If the OP wnts solids, and he doesn't mind adjusting them once or twice a year, I don't see the issue.
