Need some help !!!!!!!!!!!!!!!!!!!!!!!!!

Hmmmmm.....does not compute! It seems like the only way to get a valid measurement like this is to get rid of the head gasket tabs; any small difference in the tab heights is going to throw these measurements off. If you are going to get any good checks with this method, then I would trim off the head gasket tabs. The intake has to sit perfectly flush to the china wall all across on both ends. (And the tabs don't do anything anyhow if you are using RTV at the ends.) Did you check the gaps front and rear with a feeler gauge?

(Of course, this method assumes the china walls front and rear are of equal height. If something is goofed up front wall to rear wall, then this won't work.)

If the variation is this bad front to rear, you ought to be able to set the intake on the gaskets and see an obvious larger gap in the rear. I'd be using a mirror to check the back gaps.
