Top End Repair advice

I finally got around to pulling the cylinder head off my 1998 Integra GSR. Short version: (see this thread here for more details: Engine Misfire)
  • It died on me in January at 225k miles, while in the 8k rpm range
  • Engine burned a lot of oil, about 2 qts every 1000 miles, but it ran strong and smooth
  • Stock engine, first time it's ever been opened up.

Attached are pics of the cylinders. As predicted, one of cylinder 2's exhaust valves gave up the ghost. I want to get the car running again, but I've never dived this deep into an engine before, so I need advice. I don't want to do a complete overhaul at this time. I'd be happy getting another 30-50k miles out of this engine. I'm hoping to replace a few valves and seals and put it all back together. I'd do the timing belt and water pump while I have it apart as well.

What do you think?
  • What parts should I replace?
  • What parts should I clean or get machined, etc?
  • What else should I do?
Thanks in advance dudes.

One more question I forgot to ask: If you look at the video here back when this happened (
, at around 20 seconds in) you can here a percussive noise when I rev the engine up. I was expecting to find a piece of the exhaust valve caroming around inside a cylinder. However, I found nothing obvious that would be creating that noise.

Any ideas what could have been causing this noise? I'd like to locate it while I have it all apart.

A new set of valves should definitely be in your future.
Clean as much as possible, maybe no need for machine work.
If it's going through oil, get your valve seals replaced. (I'm one to talk, I know...)

At 225k I wouldn't spend more than a valve job and that's about $400ish. For not much more you can get a JDM replacement motor with only 45-55k on it. I'm doing my head and got lucky finding a Craigslist rebuilt head $400 then there's gaskets. iDK it's your money.
