Added some pics to summarize. Turns out (I am told) that my pushrod length is off from the head change. See the poly locks on the intakes? Anyhow, that made the rocker push the valve at an angle and start to beat out the locks. With #7 failing first....
https://www.dropbox.com/sh/ec7dcnx5cp417hq/AACmw1fhqAnM08EEeb3ueT6va?dl=0Heads are being repaired and sent back (my dime but very reasonable)
When they return, the heads and my box of parts and the block all go in for a professional rebuild, including pistons, etc and then a dyno tune.
All I will have to do is right a check (ugh) and put the motor back in and forget about this part of boating

Updates when i have some gang. As usual, thanks for all the help!
