The y8 will give higher compression ratio than a z6. Depends on a lot of variables but .5 a point is the generally accepted figure. Do a google search for "D-series compression calculator". Is this reason enough to chose one or the other? Not really. For the 1-2 hp difference, I'd take the lower compression ratio and run the lowest/cheapest octane gas I could get away with.
An obd-0 distributor will bolt on a y8 head...a z6 will only line up on two holes
An obd-1 distributor will bolt up to a z6 head...why is this important? Because the best way to run a mini-me is to convert to obd-1 and run a p28 ecu. I'm not saying there aren't other ways that can be made to work just fine, but the obd-1 conversion runs it best and gives you sooo many more tuning options.
Z6s will typically have higher miles but y8s have gotten old enough to that whatever you find could have 200k on it by now...be picky and passover a deal that sounds too good to be true.
