Headgasket leaking?

[66clow]

I was having a small leak of oil running down at my starter nuts. Pulled starter and it appears a small leak running down from the head gasket. Is this typical at times? How hard on the difficulty scale? I've replaced a engine in a Mustang and have down numerous other bolt on stuff on cars. So I'm pretty handy. Looks like it would be pretty straight forward pulling carb, intake, exhaust and head. Would I do both gaskets since I'm in there? CHEVY 350 anything else to do while I'm in there? Or actually do I just try to tighten the head bolts? Just thought about that.

Thanks
