I just replaced a S-Z with a pair of HIF's on my 76. Had the same problem
with different heights
of the two manifolds. Porter in his rebuild book and Bud Kruger(via the
list) showed me that you can
cut some large thick washers in half and use them as shims.
It worked well and all I had to cut the washers was a Dremel tool.
