I also have a 74 Z1 with a V+H pipe. However I have pod filters on mine, but run a 122.5 main, stock is 112.5.
Thats the setup its had for a long long time and runs like a champ. I tried playing around with different jets last summer, but ended up back with the 122.5's
FYI, I am pretty much at sea level in Michigan.
