[QUOTE="TD-5, post: 933972, member: 12311"] There are several variations of ported intake manifolds available, Generally there is: Stage one = inner mounting posts are milled out, Stage two = both inner & outer mounting posts are milled out, Stage 3 = both posts milled out & the dent for the fuel filter housing clearance is removed. Then there is the Elite Z MAX that has the manifold tops removed to do a complete porting of the runner interior. I think there are a couple other outfits that offer or did offer manifolds modified like this. Then there is how the mounting holes are set up where the posts have been removed, some offer pipe plugs threaded directly into the manifold material, others offer bungs welded into the manifold & ORB plugs. Some offer both options to their customers. If you go with a manifold that has the dent removed you will either need to shim the fuel filter housing or go with a filter housing delete kit. Also a lot of the factory mounting bolts for the manifold are configured with a stud on top of them for securing fuel lines, turbo drain etc, These are gone with a ported manifold. Take some time & study up on everything that's out there before you jump at what looks like the best buy. Personally I would go for a manifold that has ORB plugs. [/QUOTE]
