yeah to be honest I forgot about the crank as mine was fine and therefore re used .
You could always just buy a newage sti bottom end and bolt your heads to it [emoji6]
Either way just keep everything uber clean during assembly , check everything at least twice and don't skimp on gaskets .
Mine is noisy when cold but has been running 300hp+ for 8k mls and doesn't leak a drop of oil or water due to using all new genuine gaskets
