You can put solid lifters on a hydraulic cam (roller to roller), but you can NOT put hydraulic lifters on a solid cam (roller to roller).
Like has previously been said, the ramp profiles will be considerably different.
Your best bet would be to call the cam manufacturer and ask them if they can correct the cam to a hyd profile instead of solid.
As for checking valve lash... I've rarely found anything out of adjustment when using a stud girdle. When using Poly-locks, it seemed like I was needing to check it before every race weekend. Inevitably one of the locks would either back off if not tightened enough, or would split if over tightened.
