Default What?

Would a leak in the manifold cause a popping sound? I can't really tell where it is coming from, but it sounds like it coming from the driver's side exhaust manifold. Could it possibly be a cylinder? I replaced the spark plugs and wires. Unfortunately, I replaced them with plugs that burn hotter. I know it's vague, but any help would be helpful.
Thank you,
Doug

Don't know about popping but my 80 had a terrible ticking on acceleration thought it was the timing chain slapping turns out leaking exhaust manifold gasket.

Thank you,

Is this at idle, or at speed, or after you let off of an acceleration?
