I've pulled my engine again (third time) to try to stop it from leaking oil.
Is this futile? I've seen plenty of chevy's that are driven and don't seem to leak.
I've tried copper spray and gasket forming tubes of stuff.

I have rubber gaskets for the Valve & lifter covers and cork for the pan.

Any ideas? I've correctly torqued things with foot and inch wrenches. HELP.
