John,
  The 1 3/8" is the size that fit in my '68 152, also.  I remember 
having to run some sandpaper inside the hole to make sure I got all 
the rusty crud out, then, they fit fine.  You might want to also 
check to see if a neoprene plug will fit in if the metal plugs still 
won't work right.  The only problem with them is that you've got to 
make sure to keep the tension nut tight or they might leak a tad 
after a while.
HTH,
Myron
