today I started building my 441 heads and thought I,d share a couple tips I,ve learned over the years.

1. when going to screw in rocker studs and guide plates.. YOU MUST DRILL OUT THE FACTORY OVAL SHAPED HOLES FOR PUSHRODS TO 7/16. USE A NEW DRILL BIT WITH A DRILL PRESS...............AND USE CUTTING OIL GENEROUSLY........

2. WHEN REMOVING PRESS IN ROCKER ARM STUDS........... HEAT STUD BOSS BEFORE YOU START THE PULLING PROCESS.

MORE TO COME
