While that's being done, you should get the VSS replaced, and have the valve guides checked for wear. If the valve guides are worn, can get expensive but it's better to replace it once. Total cost of my head job with valve job, guides, viton VSS and everything was 685 with them acquiring the VSS and guides.
I had a 4-angle valve job done for less than 200 for the set of valves. Machining on the heads was in the 300 for the pair.
