hp from headers?

How much power would i get from putting headers on my 390 over stock manifolds with daul exhausts. I am looking at getting dynomax or hedman. I have a 79 4x4 and i am not sure if there are any clearance problems.

You will notice it but its not going to be a jaw dropper on a stock engine. I would recommend the flowtech or hedman headers. Many people complain about the dynomax.
