i've done 1.2 without adjustment of head - compression goes up significantly... i had to play with timing and run 112 octane to make it run right/never ping. i don't think i would recommend it unless you can get and run 112 always (and jet for it). 1.6 squish runs on 92 or better (i run 50/50 92/112) and have not had any problems with stock timing. i have run straight 92 at 1.6 and had no problems, but i'm jetted for race mix, so it wasn't optimal. you will feel a significant difference in hp, power delivery, and fuel economy at 1.6. it makes a big difference on ease of jetting also...... very worthwhile...
