I take issue with that statement that Pontiac used positive seals on the intake guides of all 67 and up 4 bbl base line motors because I have never seen such.
I have disassembled at least 80 stock heads in my life between working at a machine shop and my own motors and I have never seen such and also not to mention that the Pontiac parts break down drawing don’t show any either!
The parts break down’s only show the valve stem o-ring oil seal as in this photo here.
Note item number 10.
