I am still trying to understand why the 4 bearing cam towers cannot be bored 1mm oversize and 4 journal cam blanks cannot be ordered with 1mm oversize journals... it would seem like such an easy solution. Is there not enough material in the 4 bearing cam towers to do this? Obviously there is something I am missing here...

I went down this road, it would interfere with the cam seal on the cam drive side, the three holes threaded holes that hold the seal in are very close to the 49mm bore, there really isn't room for it.
