E Victor & MP Stage VI heads have the exhaust ports raised ~ 3/8" and spread about 1/4" over OEM heads. My Hooker 5209 2" headers didn't look like they'd fit my Challenger when I switched to the Stage VI heads (torsion bar clearance issues), so I ended up switching to TTI's 2" B/E-body headers instead.

The TTIs fit nicely and are what I'd recommend to avoid having to either or on the Hooker 2" to fit.

You should check TTI's web site for all the footnotes they list for each header application, in case there's something else you need to know for a 4-speed install, since I run a 727.
