just found out today that my x heads off my 340 re-build did not pass magnuflux. saw them and they had casting flaws (holes) right under the head gasket ring on the edge of the bore in 3 locations. couldn't of been in a more critical area unfortunetly. so here we go looking for a replacement set. anybody have or know of a set that is in good usable condition? only want the 2.02/1.60 size valves on a j-head. if not a recomendation on new that will be a direct replacement bolt on with no aggravation. been looking around and have a few in mind but cant hurt to ask the experts here. thanks.
