Are 3986336 heads worth anything to anyone?
These heads are in amazing shape. The casting number is
3986336 Mortec lists them as-
3986336....71......350..........76cc chamber
They've been completely rebuilt, They have new rockers, springs, and valves. I'm not listing them for sale...yet.
These are the same heads as the high performance ones offered that same year. The difference is the high po. ones have 2.02 valves, screw in rocker studs, and guide plates. Mine are not the high po. heads, but with a little bit of work they could be #'s matching factory correct heads for one of your 'vettes. I believe the years would be 71 and 72. All you'd have to do would be to change valve size and add ^ those two parts. Any opinions?
