Follow up to Oil on threads of 7-8 plugs. Intake removed. Valve issue? Help

If the gasket was compressed all the way around the ports and all the ports look the same, then you have no choice but to look at the guide seals as the culprits. I don't know what you discussed with the fellow(s) who put the heads together, but if you told them to check the valve to guide clearance, replace as necessary and install positive seals, then they dropped the ball in my opinion. If you did not tell them what to do to the heads, then it's probably all on you. They cannot be expected to do work that you did not authorize.

Now, if you did authorize checking the valves and valve guides and replacing as necessary and installing positive seals and they did that work, then somebody at the shop either installed the seals incorrectly or damaged the seals on installation or screwed the pooch by leaving excessive clearance between the valves and guides and you have a legitimate beef with the shop. Did you have this work done in writing and signed off on it?

I think what I would do is to pull the head and call the shop, making an appointment to take the head down there and have one of the guys take it apart while you stand there and watch, then inspect the whole mess and talk to the owner before you go any farther.
