Hi,
As far as pin cinfiguration goes, all 72-pin SIMMS are pretty much interchangable. There shouldn't be any risk of electrical damage, apart from any ESD coming from yourself ;-)
As for SIMM differences, spart from the obvious single/double sided variants, they also differ in access times, paging/non-paging modes and width. Those with parity checking are generally 36-bit, those without 32. Most amiga accelerators simply ignore the 4-bit parity.
These differences can cause incomatibilities but the worst you can expect is probably that they don't get recognised, 'random' crashes, or even a red screen at startup (RAM test error). No frying circuits and blue smoke though :-)
To answer you question, you should be able to safely test them. Blizzard cards seem to be more tolerant of these 'differences' than other accelerators. I use a pair of ex-PC double sided 32Mb 60ns EDO SIMMs (36-bit)on my BlizzPPC and they work just fine.
