If you already have to have valves installed. They will have to be ground/lapped to fit your seats in the head. You probabaly have a loose valve guide or two in the mix. If you add up the required machine work to do it right, you may already be at the 280.00 dollar cost of the reman. I would drop your old head off at a local machine shop and get a estimate on repair and weigh the cost between the two.
