318 Poly Vibration

I started with the fbbo link below, which had the same hot specs as the manual, .010 intake, .018 exhaust.

The second post links to The 318 Poly List and the details on the cold method. It states to take off .002 from hot specs for cold, but it's actually add .002, correct on fbbo.

I did all the intake, then all exhaust, using the Poly List process and adding .002 as the engine was cold.

Also, all of the springs appeared to compress the same amount, which seemed to indicate none of the push rods are bent, as mentioned earlier as a possible issue.

Only the one exhaust valve needed to be loosened, the others tightened a small amount or not at all.

The bulk of the info I could locate indicated when these engines needed a valve adjustment it would be noticeably chatty. Since mine is quiet, as far as valve chatter I am familiar with, I did not want to cause an issue and screw it up more.
