It's getting harder to figure out what's wrong. The sound sounded mechanical but it also sounds kind of wheezy. With the domes could the pistons be hitting the combustion chamber? Look for small marks at the edge of the camber dome.

You say it didn't make the noise when cold?

Does the motor have an newer cam plate?

How hard was the starting? Did you try a compression check?

Look at the condition of the rocker shafts. Are the rockers moving freely?
