Default Preparing for new head gasket

Throwing some new valves in the car and am wondering how this head looks to you all.

good to send it, or should I keep cleaning?

The car has PRC heads and had an mls gasket on it previously

Based solely on the picture (I can't feel it- that can tell you a lot.), I'd say wipe it down with brake cleaner and white paper towels until the paper towel comes back white, then send it.

When I put new heads and a new MLS gasket on my engine, I used a very large (like 12” long) sanding block, 200 grit sandpaper, and WD40. Sealed great.

If these were my heads, I’d do the same to them.

I’m old, but “send it” sounds like “do a half-assed job and cross your fingers” to me. Sorry, not sorry. 🙂

I've always used a flat Norton honing brick. We used them extensively in the Toolroom/Machine shop. They are excellent. If your so inclined, I'd call Grainger, or McMaster-Carr, and see if they have any in stock (Damn Covid!!). Generally, these stones have a tan side and a black side, with tan being the finer abrasive, and black the courser abrasive. Use a bit of fuel oil/kerosene so they don't "load up" with gunk and fine metallic fragments. You can clean them by using them on any metal surface, wetted with fuel oil/kerosene. Hope this helps.......
