intakes???
intakes??? I know of the gmpp dual plane intake swap for the lt1 but I want to swap a single plan onto mine. There was someone, I forget who, that instead of welding up the bolt holes and having them redrilled had shims made to aling the bolt to the head. Can anyone shead some light on this? Also what about the water passage in the sbc intakes? Anything need to be done to these as well.

I havent taken pics with the new holes yet, but the machine shop I took mine too was only able to get the end 4 holes of each side. The middle 4 we left alone. They say with the new style vortec heads that you dont need them any how. Still working on mine though. Your better off having the old ones tigged closed if ya can, shouldnt be to much. I had my holes redrilled and he put a small bevel in so I dont need the spacers like other people have done. You might be able to get away with JB weld, that was suggested to me so I thought I might try it see how it holds. If you have acess to some kind of milling machine, I would use it after cutting off the thermostat base. Most people I have seen mount a plate over the hole. I just used a grinder and had at it, be sure ya got some glasses and plenty of light. That stuff goes everywhere from first hand experience.

Kinda expensive, but they are ready to go if ya want the easy way f addapting and all ya have to do is kinda elongate your holes a bit then. Some other ideas I found anyhow.
