Is anyone able to tell the size of these cams by the numbers in these pics?





also i noticed some pitting on the egdes of the came lobe only, could this be cause by a lifter/hla problem?

Most cams will have ether a part number or the spec on the end of the cams. But no not going to be able to determin by the casting marks.
It's like determining someones skin color by looking at said persons hand with a glove on it.

I would inspect the rocker for the same pitting. Looks like the heat treating didn't fair to well.

If you don't see anything on the end closest to number 4 cyl I would say yes on the cam gear side.
