I have read a lot of the AA cylinders have to be turned on the lathe to deduce the deck height to 1.00mm (.0400 inch). Good new is no shims will be needed. Sound like you can get the chambers in the heads taken care of too by cc'ing the chamber's (open the small one) or fly cutting the big one to match the smaller head.
Research this sight/ web for additional information on 2056 builds Keep it up David, There is a lot of GREAT info on the page. You have one of the best resources and over all great guy checking on your thread already. Unfortunately the parts you purchased are not just drop in parts, and will need a little fitting |
