Okay, it's time to get some questions anwsered before I start putting money on the line. Right now my plan is to build a Bored N Sleeved B18C block, using the B16 head I have now for a turboable powerplant. My question, or first of many rather, is this. Do I need to do anything with the B16 block before I try and run it with a rebuilt Block? I mean does used head/rebuilt block match or does it need maint first. The valves were recently adjusted and the head has 70K miles on it. Thankx in advance.
