Can anyone attach their image for same setup but on a 4GC? I have this similar line missing but waiting to get a close-up example like this. This picture was enlightening. Thanks.
On a separate topic DaneAmerica you should consider metal tabs for the rocker cover bolts, they would spread the clamp down and reduce leaks. Right Stuff sealant is good, but you need to clean both sides well, and removing for repairs in the future might be difficult. The valve covers probably need to be straightened out at the bolts if you don't get the pricey aluminum offenhauser ones. I can see the oil leaking on to your exhaust. I used to brag about never having an engine fire and one day it happened to me with less oil than I see here on your engine.
