What happens if you mix solid lifter? Would there be a problem doing this or is it a bad idea?

Do you mean mix up used lifters when reinstalling on a used cam? If so you will almost certainly flatten a lobe or ruin a lifter.

Well kind off but what I was looking at doing was using a sligthly used set of 14 and get two other to go with it. I know, "cant reuse lifter or they will cause cam failuer". Yes you can and I have done it twice without problems only on a hydralic cam. If you take a lifter in good condition and get a piece of fine emery cloth and lay the cloth on a smooth hard flat surface, then stand the lifter up on the end(cam surface down) and move the lifter in a figure eigth pattern, sanding the end just enough to resuface it, it can be reused. I have herd of taking the expensive harden ended lifters and putting them in a lathe and truing the end and then sanding it like I said and that working as well. Only reason I dont get a new set is that I am broke from other repairs and was looking for a cheep fix so I can get back to racing. I lost two lobs on this cam from improper brake in(used the big springs without changing them for brake in) and I'm short two lifters. I know you use to be able to buy just one lifter and was hoping I could still do the same only with a solid lift cam.

That procedure with the figure-8 resurfacing of lifters, was in a book by David Vizard. If I remember right it was Perf Chevy on a Budget or something like that.

The figure 8 motion puts a little crown on the lifter, it doesn't leave it flat.

Also, several machineshops around the area (PTM, JRs) are now resurfacing lifters. No idea what it costs tho.

Sounds like you already made up your mind to run the "gently used" lifters on your new cam, so go ahead , give it a try and let us all know at the end of the season how you made out. I certainly wish you the best

I run used lifters all the time if they still look flat. I never have had problem with flat lobes.

Well maybe I just got lucky. I havent tried it in a race motor just on a daily driver. So maybe I shouldn't try it. I dont want to tear this thing down again anytime soon. Sounds like know one else has tried this! I was getting a little desperate to get back to the track but I found a couple more sponsers for just enough to get me going again.
