[Fot] 6 cyl cam bearings

[Larry Young]

I know this has been discussed, but I must have been asleep, so I 
apologize.  As I understand it, if you want to put cam bearings in a 6 
cylinder TR, you use Spitfire 1296 bearings (1 or 2 sets?).  The block 
must be bored from 1.9680 - 1.9695.  The bearing journals on the cam 
must be ground to fit the bearings.  Doesn't this restrict the cam 
lift?  What is the cam bearing ID compared to the stock setup with no 
bearing?
Thanks,
Larry
