They just showed up tonightNope, older HP mold with lower quality casting that some have casting flash/flaking issues, sent them back....could be blems, could be mine LOL.
Take a machinist file to it, watch out for possible casting flash in the booster entries, make sure they are straight as well. They flow more then advertised for the most part.
I'll take those old 4781's that nobody wants off your hands 1980RS LOL.
