First time engine build won't fire

Okay guys this oil leak is getting tough to diagnose. It didn’t appear until much later than the initial break in and I thought it was the oil filter but an oil change and retorque of the filter plate I still had it so I got it running and warm and took it for a test drive it didn’t appear until I go from low speed 20 to 25 cruising to some real rpm 45+ and I have identified it to be coming from the top of the block and I’ve ruled out the usual suspect of sending unit which is a mechanical. It Almost looks like it’s coming from the distributor which I read on here of guys sometimes having rtv stuck under the distributor shaft where it mounts so I plan to check that. It’s running down the right side of the block and dripping onto passenger header making potential for fire not to mention I don’t want to run out of oil for obvious reasons. Do you guys have any suggestions to look for ? At one point I was worried my head was leaking at the back and it’s not a valve cover as far as I can tell they are actually holding oil well. I may also pull the intake and reseat it.
