318 with Edelbrok perfomer intake and 600 cfm 4 barrel, what headers please?

Many thanks to everyone for the contribution and info. I can see that there is other things I can do before I get to the headers. I am not chasing seconds, what I am after is a grin on my face every time I take the old girl out. All about feelings for me and for that she has plenty of charm in her as is. I will sort out the stands first, and then in the future go with the cam and headers. Thanks
