Flames at the head are normal. Actually it's the exhaust you're seeing. Out the tailpipe or backfire is probably because the headers have now caused a lean mixture in the engine. Burnt valve you'll usually here a compression sound out the tailpipe. :I have a 72 Maverick with a 250 6 cyl, with headers, and I have put a 2bbl carb on it. My header gasket is blown and I am waiting for the new one to come in but when I have been driving it around and a couple days ago it got alot louder. When you hit the gas and let off quickly it backfires. I was driving at night and noticed that it shoots flames out the exhaust pipe when it backfires. I am wondering if a burnt exhaust valve could cause this or if its just because I have too big of a carburator on it.
:any help would be appreciated
:thanks
