Stainless steel valves need a hardened steel tip, this can be verified with a magnet; the stainless steel stem shouldn't be magnetic but the tip should be.

I'm a little late in mentioning this but if you don't plan on taking the engine over 6200 rpm you don't necessarily need to upgrade to single groove valves, valves designed for the OEM 4 groove locks are good for service up to 6200 rpm. The important thing is to eliminate the OEM valves which have a nasty habit of failing while the engine is running. 4 groove valves can be sourced from Speed Pro or Melling. Speed Pro doesn't currently have a listing for 2.19 intake valves, but Melling does. Both have listings for the 1.71 exhaust valves.
