i have a d16a6 (sohc zc) bottom end and i would like to get a y8 head to have higher compression. Can I put higher compression pistons in d16a6 (sohc zc) with the y8 head to make it even higher then it would be. The compression im looking for is 11.7 or a 12.5 and I would like to keep using 93 oct nothing higher.i
