Valve grinding compound/paste.Polish it some,but dont go overboard with it.Spend the same amount of time on all of them.

Grinding compound will not correct the problem. Only aggravate it. Take the head to a machine shop. Have the valve guide checked and the seat cut with a Serdi type cutter or a well dressed stone. A decent machinist can fix this correctly with minimal material removal.

Bob's right it's a great time to get some really nice 3 or 4 angle valve seats cut.

valve job

Don't be pennywise and pound foolish. The heads are off. Go get a good 3 angle valve job and have them do a pocket port at the same time. You'll end up with no worries and a good running, long lasting pair of heads.
