Was it the #3 rod? I've never seen bearings for what you're talking about. It seems like an awful lot of work to avoid finding a small journal cam. Perhaps your existing cam can be machined down to the correct size. But I'm with Joe on this one - leave the block alone.
If you haven't already, seriously consider enlarging the oil galley in the block as per the competition prep manual. It helps that #3 rod bearing live longer. I don't know if there is a trick to putting the bearings. I was considering doing this when I did my 1500 several years ago, but decided to let it ride. Joe - any wisdom on installing the bearings in the block?

That way you don't have to bore those journals. The Mk3 for example had cam bearings which use the same size block borings as the 1500 but have the cam journals sized smaller so the bearing will fit between the block and the cam.

My cam looks like it is in good shape and is only a couple years old. I will ask shop to verify. I am thinking about having cam bearings installed - I have read arguments on both sides. As I understand it, the normal process is to install cam bearings then use an earlier small journal cam. Is there a bearing set that will allow me to use the large journal cam I have? I realize the block would have to be bored out to accept larger bearings.
