I used white "ceramic" VHT header paint on some raw headers and that stuff dried like glass. These were drop in Ford 351C car headers, could pull them in 10 minutes and not even nick the paint. Are Dougs ceramic coated on the inside? They usually rust from both sides
I saw a streetmaster once and the plenum was tiny, didnt think it was worth the time. bought a StripDominator instead. It was the airgap before the Airgap. 340 with 3.91 rear and a MP 284/.484 cam in a 2900 lb A? lots of power....
