I'm going to be buying either a zz4 or fb 385 the end of this month. I'm looking for some header recommendations for either motor (manufacture and size).

Thanks,

I have a set of Doug's D368 for my Fastburn 385. The fit is okay except it is real tight to the aftermarket idler arm. I have about 1/4" clearance on the AGR steering box. Haven't started the engine yet so can't comment on the the seal to engine. Underneath they tuck up quite nice.

At some point I would like to install a power rack and pinion from Flaming River. From what I have read it sounds like you have to use their headers when using their system. Has anyone used their headers or know how well they would work with either of the two motors I'm looking at.

I had dougs d368s on my zz383, the fit was perfect. They don't hang
low, fit great along the subframe. Make sure you use a good d port
gasket on them, I tried an oval port type because nobody had them
in stock around here and had some small leaks.

One other thing to add. The D368's work with the stock clutch Z-bar. Not sure if your going manual or automatic. I just about got caught out ordering a set of Hedman 66609, but noticed just before I ordered that according to the catalog, they won't work with a manual clutch. Just another thing to watch out for.

I also have the D368's with Fastburn heads. Close (1/4") at idler arm, but fine, and plenty of clearance at the PS box. Excellent part.
