Black RTV is the only truly oil resistant sealant for engine assembly. IMHO.
If it is a high hour engine I would advise you to replace the camshaft bearings.
The last time I had a machine shop make a cam bearing driver it was only $20.00.
I had it made so that the small diameter of it was long enough to scribe a line on it for reference to get the oil hole in the bearing lined up with galley (hole) in the block.
It is very frustrating to install a bearing only see it is a half a hole off. You can see the alignment with a flashlight looking down the galley in the block.
