[AMC-List] Unshrouding valves

[Nick ALFANO <71amx@xxxxxxxxxxxxx>]

Rich,

I am assuming you are referring to the 360-390 head
and not the smaller engines.  That being said, what
you want to do is take a head gasket and scribe the
inner diameter on the head where the valve meets the
edge of the chamber.  Remove most of this material
transitioning your port work into the floor of the
chamber.  Smooth out as much of the material that is
constricting the air flow so the that intake and
exhaust gasses can freely move around the entire
circumference of the valve.  Best way to do this if to
have your machinist cut the material out with their
mill and then smooth it out and polish with a dremel
or die grinding tool.
