I would send the jug out and knock .030" off the top and then put it back together with a .015"
head gasket from Dax or Juice and that should bring you in the neighborhood of
.012"-.014" . Start with a #8 plug and if she runs hot jet up 4-10s and then if she runs hot plugup!! Thats what we streetracers in St.Louis do. Fred would tell you the same.
