Default 3-angle valve grind vs. "standard"?

Just getting my ducks in a row in anticipation of a valve job on my baby.
  • Any ideas on what a 3-angle valve job is worth in HP gain vs. the standard fair, as it relates to a 485-500 hp LT5?
  • And, would a 3-angle grind usually be accommodated with new guides as well?

And, one un-related Q regarding the TB: What are the real gains from porting the TB on an otherwise fully ported 350 LT5?

TIA,

P.
