Stainless valves and lash settings...

Factory 99 valve lash is 7thou intake and 10thou exhaust. What about when using aftermarket stainless valves? I know stainless grows a LOT more than normal steel. I have seen cars on the dyno with stainless exhaust grow a couple of inches.

Thoughts?

Never heard of it being an issue. To make you sleep better, you could easily check the lash when the motor is at operating temp to see what the difference is.
