I cut a piece of 1 inch PVC pipe and put a good notch in it, got a big C Clamp, put the pvc pipe on top of the valve and used the c clamp to compress the valve spring till the valve retainer clips just popped out. Removed the valves and springs (keep them in the right order because they need to go back into the same valve guides). Once I got the valves all out, I cleaned them all, cleaned the head real good, then changed the valve seals, got me some grinding compound to use on the valve and valve seats and put it all back together. Make sure if you do any of this or just change out the one burnt valve (changing out the one burnt valve should also require you using the valve grinding compound then cleaning it), that you do a Leak Down test while the head is still off. Good luck. Keep us in the loop on what you decide to do.

FX4Mark,
I don't blame you for sending your heads in. If you've got any machine work to do, it's a necessity. Good luck and keep us posted.
