Ls/vtec b16a2 head b18b block

well i just bought SK2 stage2 cams with springs and retainers they are sk2 as well. got it for a good price 500 miles on them from an ITR one my buddies sold it to me, $650.

now i am looking for SS valves, perhaps my buddy sold his after he told me about the cams etc. well he said use Sk2 valves. now i would have all sk2 valve train. i was thinking about supertech SS valves or should i stay with sk2? any experiences or problems let me know!
