Mystery - Strong Fuel Smell
Well, it's not
us that have to be happy, it's you. Looking at this pic, I see the fuel filter still in the wrong place, and it's upside-down (this is worse, not better), fuel line is still metal and still runs close to hot head and header...doesn't look like you read post № 2 in this thread at all.
(Also, do yourself several enormous favours including making a big improvement in the fuel odour problem:
wrap those headers clear all the way from the head down to the collector flange, then start wrappin' again for at least a few feet of the pipe behind the flange.)
