WHY?

Lay it on the engine and take note of the relationship between the end walls and the port and bolt hole alignment. I am betting that intake has been milled. Shouldn't be hard to tell. You can still make it happen......I mean dammit you have the intake off........you COULD take the heads off and have them milled to match but you're going to need to determine if it's been milled and how much first.
well, the intake was new..I bought it new, no box. You can tell its never been bolted onto an engine and never had bolts installed in the EGR block off or anything..They offered to give my money back but I am heartbroken. I have wanted an intake for a LONG time and finally got one and it doesn't work. Hell, no I am afraid to buy another one. I WISH I had someone close by with a few aluminum intakes they would let me bolt on and see if they would be ok or if something is wrong with my engine..Shouldnt be the engine..when I pulled this engine out at the junkyard years ago, the heads needed a lot of work, so I just went back to the junkyard and got another set of heads and had them rebuilt and my factory iron intake had no issues sealing up with ONLY the valley tray..no sealant or paper gaskets at all. This aluminum intake has the valley tray and paper gaskets on both sides of it and STILL wont seal! If there was enough 'meat' between the top of the ports and intake edge I would just plaster RTV or something on it, but there is only a small amount of area above the port windows on the intake and I don't think it would last long before leaking through the RTV. This just sucks! Anyone got a spare aluminum intake I can try to see if it will actually work? Damn I really wanted the street dominator!
