Fixing an exhaust port with epoxy won't last long.
I'd be very careful about fixing heads near the seats. That is VERY hard to get right, and it's best to pay the price and get a reputable shop to fix them. You get what you pay for when it comes to specialty work like this.
There's a guy in Dallas or Mesquite maybe, who's well known for only fixing aluminum heads. His name escapes me now, but I am sure SOMEONE on here knows him.
FWIW, part of the high prices in head repair come from needing specialty welding equipment.
