Piston pin bad ?

Plenty of oil. Puddles in valleys of head.Oil poured out of shafts when I picked them up .
Grooves to the bottom as evident by the location of wear marks!

I wonder if the clearance of the rockers on the shafts was just to tight ? But if aluminum expands more than the shafts I wouldnt think that would be the case...of course they would have to get hot first and that could take a while .
