Let the machine shop tell you what to do.

Any decent machine shop will take a head with the cams still bolted in even with the cam gears still on. They will take all of it off so, like stated, the valves will be closed allowing for the sealing surface to get cut. They will replace the cam seals, torque all the caps to spec and make sure they get installed into their original order.

I would just take the head as is to a good machine shop and have them figure it out, they will let you know if you need a new head or not, my guess would be the head is fine.

yeah i took the head to a shop today and they said they will see what they can do about that problem (he said they will tey using cheese cloth) im getting the head maged and milled and possibly a valve job which comes to a grand total of $400 for the head to look like it just came off the factory assembly line

Have a better picture of the "gash". The surface looks a little rough, if you're going with an OEM HG it's fine if you're going MHG I'd lap it.
