My first post on this BB. I have a '69 with a ZZ4, Vintage Air, 700R4, PS, PB. I am looking for headers that will fit the angle plugs and D ports. I like the Thorley's 14 ga. but Summit says they only come with the nickel chrome coating, not ceramic. Summit's recommendation was 18 ga. Hookers for $466 coated. Doug's are $550. Who has well made headers at a decent price?
