Valves, Valves, Valves... In my endless searching I really didn't get a clear answer.
I need to replace the intake valves in my 317 cylinder head off my LQ4 build.
Seeing that it will be my daily driver and my goal is to get about 400hp off this block plus the possibility if nitrous shots in the future. I was wondering if the stock replacements from Sealed Power would be reliable enough for the work or should I look for a better upgrade?

Machine shop is saying that the intake valves are just slightly out of round, and the exhaust valves guides need to be serviced as well.
I was looking into Engine Tech or Manley valves as possibly upgraded replacements. I do plan on sending the heads out for CNC porting as well.
