Headers on Ramcharger

Which headers fit best for the money?
Doing a budget 318 swap in my 85 D150 SWB and exhaust is going to be one of the bigger expenses.
So far I have a slightly warmed .040 over 68 318 with a Perfomer and Purple Shaft 268 cam advanced 4°, with a 10,000 mi since rebuilt 727 out of an LRE, a couplle different convertors, and an Edelbrock 650cfm.
