It's that time again. I need to replace my 454 exhaust manifolds and risers. Can anyone give me a recommendation where I should be purchasing these? My 454's are freshwater cooled. Also, I see two styles; center and slightly off center. Any advantage to either?
Thanks in advance.

I googled for a couple of days and found the best price for manifolds and risers at the url below for my Merc 350's.

John-
I have the old log style. I remember that someone posted at sometime (narrows it down, huh), that they had gotten an aftermarket center-riser manifold and when bolted up it didn't clear the engine box. So, make sure whatever you get, you have adequate clearance. Apparently they're not all the same.

:When I had the gassers ...(Mercruisers) I used OSSCOs?Purchased in L.A. somewhere..
Usually the manifolds last far longer than the elbows..
