If you have an old Holley with the original or even some replacement gaskets in it, you can expect it to leak because the gaskets have shrunk. Even if they don't leak or stop leaking, you likely will have probelms because the metering block gaskets have shrunk and blocked some passages.
When they leak, some ham fist comes along and cranks down on the bowl screws thinking he will stop the leaks. He won't but he will succeed in warping the metering and main bodies of the carb and then all you have is a pile of junk unless you can press the parts back in shape in a jig.
The biggest enemy I have seen to a Holley carb is what I just decsribed. Fortunately, today you can buy gaskets that don't shrink, don't leak after sitting dry and idle.
