Welded combustion chambers?

To get to 60cc with a 2.02 valved 360 head... it usually only takes about .060-.080 , some cases a hair less. The heads can be anywhere from 69-74 cc as cast with part of that due to valve size and the amount of chamber they take up... just like tulip 2.02 int port measure 155cc while 1.88 versions measure 160cc..

Roger..... I was running with approx .005" cut for each cc, and starting with a 72-73 cc chamber, and getting to the low 50's IF you took all of the open area out to get to a 'closed' chamber. Taking off .060" would get to right at 60 cc's, but more milling would indeed be needed with a tulip valve head shape.
