Is it possible to convert Shimano 600 SIS to a STI lever system? is this possible with a 6 speed set up?

Short answer,yes. Easy way is to find 7 speed rsx(ebay) or or 7 speed sora shifters, as 7 the 7 speed cog spacing was the same as 6 speed index.Your rear derailer will work and probably the front too if you have a double chainring. If you have a 6 speed freewheel you could replace it with 7 speed one,but a 6 speed cassette is differrent story.
