IS SOMETHING WRONG WITH 340 LIFTER BORES

Those globs on the lifter casting bosses are bits of core sand that fell away as the cores were removed. You can smooth them out with a grinder if you want, the factory didn't bother to deburr much on production castings. As for the bores themselves, since the lifters look a little rusty, there may be some pitting. Not a huge deal generally. I lightly hone (using a piece of emery cloth in a shotgun cleaning "eye" rod spun with a drill). Just knock off any loose corrosion and high spots. Better to leave some light pitting and discoloration in place than oversize the bores.
