Should I remove and re-fit the cam bearing?

Quick question.
The front cam bearing in a block I have has been fitted so that the oil journal in the block and the hole in the bearing dont quite line up. The bearing obscures the hole a little bit. About at leastthree quarters is ok though. Should this bearing be removed and re-fitted, or will oil passage be ok? Its being built as a stocker and not a race jobbie.

I think you are right mate. Spoke with Derek Dave and John at Chelsea on Saturday night, and they all said it should be changed. Best to do it now, rather than when it starves itself of oil 6-months after I have spent all this time and money on it.

After all this time looking for someone to press it in, was given some tips from a freind builting a replica GT40 and did it myself - just clouted it in over the top of the old one with a lump hammer
Only joking.
I stuck the bearing in the freezer and packed ice all over it yesterday morning. In the afternoon, I globbed loads of grease on part of the existing bearing (away from the oil journal) and cut it with a hacksaw blade (grease holds the swarf in one place instead of letting it waft into engine). Then collapsed bearing in on itself and removed it.
Put a blow lamp around boss to raise temp a couple of degrees (took ages as heat dissipates blummin quick). Took bearing from freezer, smeared it in grease, lined it up in block, piece of perfectly flat timber on bearing and tappity tap tap with hammer and it slid straight in. Perfect job, no deformation, oil journals now line up, NOW i can get on with building my engine.
YES!!!
