Ph is a factor but it isn't be be all and end all. 8.2 really is high for rams, but it's unusual for tap water to come out that high.
All your fish naturally come from areas where the water is quite soft. I would say anything between 5.5 - 7.5 would be tolerable for these fish. As long as you are within a tolerable range then your fish will adapt if properly acclimated. It is the jump or drop in ph from the lfs water that would be stressful.
To do this you can drip acclimate them, or you can simply keep adding small amounts of your tank water to the bag when you bring them home at 10 minute intervals or so until there is half of the lfs water and half of your water in the bag. By this time they should have adapted well enough to go into your tank without issues.
