I was just at the Judging retreat and we enjoyed a 59 fuely for the day. Beautiful car but when we looked at the heads it was confusing. Both makings were on the heads, the triangle on one end and on the other end the multiple bumps. The Master judges thought the heads were wrong. So as soon as I got home I looked at my 550 heads dated Nov 58 and they were the same, triangle on one end and the multiple bumps on the other end as is drawn in the judging manual. Rereading the manual I am confused as to what should be on the end of the head for 58-60 cars. Can anyone help me with this? Tom
