Oversized valves in 823 ls heads

[Malachi3700]

I am probably posting to the wrong thread, but here’s my question:
I have a set of 823 ls heads that I am going to get ported and get oversized valves put in. From my little bit of research, ls7 intake valves are 2.2” in diameter and exhaust is 1.625” which is the size I am going for. Will stock ls7 valves work for my application? I can’t really seem to get a straight answer anywhere
