Make sure they stay on centre when they bore the cam bearings. It only takes a little error and the backlash in the timing gears is either too tight, ruining the gears or too loose which is noisy. Both drastically shorten timing gear life. I believe the distance between centres is 4.155"
 
If you have a early engine block there is no passage way from the valve chamber to the rear cam bearing.

There is a article in the Service Bulletins that instructs how to drill the passage way to the rear cam bearing.

Ford used the pan rail as the datum for machining. Read this link,and print it off for the machine shop if you want to.

Ford did not use the pan rail as a reference for machining.

He used a Rear Main Bolt hole, and only one of those in particular.

It is the left one, a Reamed main hole, opposite side from the valves. All re-manufacturing operations must start from this point.
