Are you still having trouble getting oil to your rockers? One cause can be by not replacing the one head bolt with the oil passage built in. The factory bolt is drilled with a 1/8th hole which allows oil to rocker shaft. I beleive '55 to '62 235 heads had this bolt. It has to be located in that oil passage hole. Good luck, Greatdane
interesting, none of my head bolts were drilled though, and the numbers on this block come back to a 56. i installed all the head bolts where they came out off. the oil does make it up, it just comes out around that little tube instead of into it. i'm looking into making a sleeve which might solve the problem. thanks for the tip though!
