What do you consider low pressure and what viscosity oil are you running? Don't be too sure about header leaks. You'd be amazed at how much they sound like metal on metal. A bad leak and you'd swear you threw a rod bearing. Make sure your head bolts don't interfere with the flange of the header. Not sure if this is a problem on small blocks but it definitely is on big blocks with the right combination of head bolts and headers.
EDIT: Good luck, know you've been having enough engine issues and don't need anymore.
