Not sure but I think the Moroso Kit and the Mr. Gasket kit are around $28 and they come with the one way valves.
Heres what happened .
I originally had straight headers (set #1) with out the tubes . I bought a kit . Ralph gave a set of twisty headers (set #2) that already tubes in them . I wanted to run my original straight headers (set #1) for testing purposes so I welded the tubes that came with the kit to my original straight headers . I scored an awsome deal on a diffrent set of straight headers (set #3) and they do not have tubes in them . I will not be running (set #1) my original headers anymore and I dont want to cut the tubes off . I am not in a hurry .
So , what time will the train get to Chicago
