Having some oil issues...

I have a 1976 cb750k SOHC. I bought it and wasn't sure how long it had been since it had an oil change. I got some synthetic 20w-50 oil and a FRAM ch6009 and put those in. I did not put in the new oil filter seal, because it looked different (smaller/round). It started to leak oil from the pan bolt and the oil filter housing... So, I figured it was because I used synthetic oil and/or didn't change the oil filter seal.

I did another oil change and used standard 10w-40 and again went with the FRAM ch6009 filter, but this time did change the oil filter seal. Now it's REALLY leaking oil from the same places when the oil heats up.

So, is this an oil viscosity issue? or something else?
