SPEEDMASTER ALUMINUM HEADS

While I’m sure there are plenty here who got a nice set of cast and machined Speedmasters the set I got had a few too many machining issues especially the rocker stands radius not matching the shafts (oem or the Ersons I have, the shafts were loose) and a couple rocker stand heli-coils not installed correctly, and the valve job on the seats were’nt very good so I unloaded them and went with something else.
