Connecting rod length

[Roger]

Howard,

Thanks for your reply, 
I did that when I had the assembly out of the crankcase it went through all four but No. 4 was a bit tight because the small end bore was a good fit.
So that must mean all the rods a are the same length within the white metal?
The crank case top face is flat now I have taken the bumps out round the studs.
The block is parallel within a few thou.
It looks like it all checks out ok but I must have missed something.
