I was going to build both but have decided to got the y8 head and both a fully built sleeved bottom end so no longer need it. I have a z6 head with everything with 89K miles on it and a y8 block including gridle and crank with 56K miles on it The block I may keep as extra unless good offer comes along. Shoot me an offer pm or email me at adm7328@yahoo.com I am looking for a Y8 head if you have one to trade.
