installing intake is a B****

The intake should go right on and the bolts should slide into place if the machine work is done correctly. You can move the intake around a little bit by using thinner or thicker gaskets. You can get paper gaskets as thin as 0.015 or as thick as 0.060 which gives you some adjustment. If you can't get stuff to line up with gaskets then you have some other problem. Either the deck was cut or the heads have been cut or someone messed with the intake. If everything is correct you should be able to change intake manifolds in minutes. I just finished up a dyno test session where we changed intake manifolds and had the engine back up and running in less than 15 minutes.
