Did GM ever put 2.02/1.60 valves in these heads?

In 69 did they offer screw in studs and guide plates on these heads also, and would they have been only available on the DZ camaro?

No screw-in studs or guide plates until 1970. I am pretty sure the 186 "DZ" heads were used in Corvette 350 engines.

the 186's with 2.02 valves would have been used in the L46 350 350 corvette only.

Tried to find that info for sure, but could not. Was that a hydraulic cammmed motor?
