3.8l "8445" GN-type heads for sale.

I'm trying not to be a hoarder of parts, so if it doesn't fit my current fleet it's gotta go. These are the 25518445 hi-flow water jacket heads used on HP 3800 motors. Complete with valves, springs, rockers and shafts. $100 for the set, pick up only. Western NH just north of the MA border.
