Thanks Guys, the placement of the engine tin is what prompted this inquiry. When the engine parts went to the machine shop, the head that was on it at the time went with, that's why it is so clean.
Then, when I started to mock up the engine, finding all the tin etc, I had to start taking apart the parts engine. That's when I found out the top tin (that was missing from my builder) wouldn't fit because of the plug placement in the original head. So I started robbing parts from it. Which, when I pulled the head, I discovered would have been a better choice for rebuild as it is still std bore!! I'm too far into this one now to turn back though.
AS it was, I had to go .030 overbore on the 126 block plus .010." on the crank & rod!!
