I fly-cut the heads to remove the step in them and clean-up the mating surface to the cylinders.  After cc'ing the heads and figuring all the other info, I cam up with 8.5:1 for the static compression ratio.  I did not make any other changes that I remember.  Stock cam, stock heads otherwise, stock Solex carbs, stock 66 distributor.  I have never had a problem with the 87 octane gas and I mash the gas and shift at 4k+ all the time.
