I’m overhauling my engine right now and I’m at the point of doing the valve job. I have new guides and valves along with a reamer and lapping tool.

I’m not taking it to a machinist because it’s a 4 hour drive one way and I’ve done all the work myself up to this point.

My question for you engine gurus is this: If I replace my valve seats will I also need to have a cutter tool to fine tune them or will the new seats be ready to lap with my new valves right off the bat?

I’m wondering if it’s better to get a neway cutter tool and salvage my existing seats. They aren’t in great shape, but they aren’t beyond re-cutting either.

If I go the route of replacing them do you have any tips or tricks for getting the old ones out? I’m very skilled with a dremel/ die grinder and was thinking I’d cut some relief slots and pry them out. I have a press for installing new ones.

Any other advice on doing your first valve job?
