I got some slight damage to the block from the cam, seems like maybe the cam button spring pressure been too high and the cam slightly scratched / rubbed against the block machined surface facing the front cover ...

I'm have the block at the machine shop currently for line honing etc currently and they pointed this out to me. Having a roller cam setup installed but not sure what to do about the engine block surface where the cam sits?

Any ideas / suggestions?
Do a search on here or TBs, there are some who had it machined to fit a roller thrust bearing or a solid brass shim/bearing .
