4.6 timing problems
Engine will only rotate 180 either way (by hand with a ratchet and socket) before something hits internally. Everything seems to be correct as far as I understand. I have attached pics of what I have. Any help will be greatly appreciated.

crank gears marks are at the 6 o'clock position with the red links on chains lined up
Did you stretch out the chains like l=============l to make the marks? The links on either end are the ones to paint. What happened to make yo take it apart in the first place?
Yes the chains were stretched and marked l========l . It initially blew a spark plug out of the #3 cylinder. The head was removed to fix. After initially getting the timing incorrect and breaking 3 valves and bending one, my friend got a "new" used head for it. After sitting for awhile he is back to messing with it and is hoping to not repeat any mistakes.
If its in time then something has to be on top of a piston or maybe a rod got bent and the piston skirt is hitting a crank counterweight. I know it's too late but there are repair kits for the stripped spark plug holes that don't require removing the head. Cal-van makes a very good kit and I have installed maybe 20 and have not had one come back.
