Thanks a lot for the video! I just read this whole thread and maybe I missed it but are you running the valve job as is? Are you going to lap them in even though they seal?
yes, running the valve job provided. If I was to pay my machine shop, I'd have put my own hardware in the heads. To me, at least, the only purpose to buy loaded heads is save the $$$ and run the provided hardware - after a home inspection.
