hell yea man! i could see that being an issue but it looks like they're just sharing the top plate to keep the cost down by not coming out with a whole new short version but it's just too much of a bend this way.

I took my Hi Ram and had it flowed last week on my heads and a set of Mass Motorsports LS3 Small Bore heads.
So far it looks like it is a very good peice. My old ported GM Performance Single plane intake dropped the flow on my ported heads about 10 percent but only dropped the flow of the Mass LS3 Small bore head about .5 percent (these are very good heads for the small bore engines (LS1 bore)). Keep in mind the GM intake did not have a TB on it but it does have an elbow.
Something else to note, the stock LS3 manifold kills my head and the Mass Motorsport LS3 Small bore head, and the Fast intakes? Well they are better then stock but no were as good as the single planes even with the elbows, at least on these two heads.
The Hi ram did not reduce the flow numbers of either head and it had the 92mm TB installed on it! I left it with the shop becasue they wanted to flow it on a set of Mass Motorsports LS7 heads he had there. I will post up the results of that test when he is done.
So far the HI RAM will at least keep up with m heads and we will see this week what it can do on the MMS LS7 head. I would say the improvment through the intake will be worth the trouble to modify the car to fit it.
