4.526" (for some unknown reason, I have it memorized)

Stumped me on that one. I do not ever recall seeing a spec
in the book. Spring stacking (with a super high lift cam)
would be more of a problem then stem height. Might be checking
the head was done correctly, if previously reworked.

>Are there any other specs that he might need???    

Nope. Just make sure it is FLAT on top and bottom, so the
cam doesn't bind. 

Cheers,

Tom
