So, I put my motor all back together and had a noise at startup that I was thinking was the starter. Turns out I think my valves may be too tight.
It's a 52 Merc with Edelbrock heads, and adj lifters. It was really noisy last summer so I was thinking valves needed adjustment. When I went into it I made cold adjustments of .014 intake and .018 exhaust. All of them seemed to be loose, which is what I expected from the noise. Although the engine was running great before.
So does this cam grind need more clearance? What should I set them at?

Thanks,
Ralph
