I recently bought some conversion cams from ebay advertised as "andrews #26" They are conversion cams but dont have 26N stamped on them, instead this is what's stamped on them "RACE
88C 56662 MWM" Has anybody seen this before?

Eh Hairless

Typically all Andrews are stamped to their specic grind ... a call to andrews will do the trick ... ask for Gary Wallace ... he will help ya out, nothing like hearing it from the horses mouth

I looked at some of andrews other grinds and they seem to be the same as the 21 except with a higher lift. Would a .520 lift be too much for stock springs? What kind of set up would these cams be good for?

99-04 stock heads are only rated for .510 lift, 05 and newer heads will be ok. Also, the guides would need to be cut down some.

Would guides need cut down on 05 and newer heads?
05 heads will be ok with that lift, nothing required to be changed or machined. That's the year HD changed to beehives and 7mm valves.
When you install them, you can turn the motor over with the rocker cover off and look at the valve stem. The spring retainer shouldn't hit the valve seal.
S&S sells .585 cams as "bolt in" for 05

I appreciate your help. I measured the base circle on these cams and then measured from base to high part of the lobe and I'm only comming up with a difference on .32. Does that sound correct in measuring the lift? Can I measure that way?
Thanks.

Yes and no, you have to multiply that number by your rocker arm ratio to come up with total lift. Ex. .32 x 1.625= .520
