Okay so I really enjoy reading build threads but I always get stuck on what I can do on my own engine and I end up reading about what cam everyone is using and what not. It's a bit silly as my '75 Imperial is not that good and I'm pretty much using it as a learning project.
So to get my mind off it I did a compression test and yes it's a worn old engine, readings around 105-120 psi dry. Wet test had only minor changes so I'm thinking bottom end is okay. Don't mind the numbers that much as engine was cold so so far so good. Only issue is #2 cylinder which was at only 88 psi
Can I hook up my compressor to the cylinder to confirm it's a top end issue? If yes, what psi should I run that? I don't have a leakdown tester.
I'm thinking about pulling the heads for my next project. So now for the real rookie question, sending the heads out, that means cleaning, skimming, valve guides and valve seats right? Should I expect needing to replace valves or can those be cleaned up generally speaking?
I have little experience when it comes to heads so trying to gather information before going further. Any and all advise will be appreciated
