It's an interference engine, had to hit a valve, and you have to assume bent it.
I once put back together, on the timing marks, a 9000 engine that the owner had done a head gasket on but didn't release the chain tensioner. I'm not sure where it was timed to, but it plainly had jammed while running. (Owner swore not, said it just wouldn't turn all the way over so he gave up. But he must have been lying.) Valves all seemed to be seated, not jammed open. But engine once correctly put together had like zero compression on three cylinders and wouldn't even start.
You'd need to pull both cams and put engine back on the marks to try yours out, but it's probably not worth the work. Just presume it bent valves, pull head and deal with it.
When installing cam sprockets, you need to make sure the key is exactly lined up with the keyway and then seat sprocket down home all the way by hand. Then tighten bolt to correct torque holding cam with a wrench on the flats. Don't try to suck the sprocket down into position with the bolt, you can shear the key if it's not lined up dead on.
