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

Here are the measurements I got from the intake manifold. As instructed, I sat the intake down on the engine with clean surfaces and no gaskets. I slid the intake to one side and kept pressure on it with one hand to be sure it stayed flush with the head. I was using Edelbrock .060" gaskets.

.042" at first intake bolt hole
.048" at first set of intake runners
.056" at rear intake runners
.0585" at rear intake bolt hole
.055" gap at front between china wall and intake
.050" roughly at rear china wall and intake, kinda hard to measure there.

BTW, I may have not interpreted these last 2 measurements right. In the measurements of the gap between the china wall and intake at front and rear, are these made between the bottom of the intake and the top of the china wall? On one side or the other or??? And were the .055" and .050" gaps between the intake and china wall perfectly even across from side to side?

Here is what is baffling me a bit, with our new Edelbrock heads and intake on a 340 LA block: there is no way I would have been able to set the intake on the engine and slide it over to one head. If I pulled the gaskets, then the intake would drop but it still would have a gap to the china wall and be in contact with both heads. You can see a pretty large gap between the bottom of the intake and the china wall, especially in the 1st pix. (Maybe I am mistinterpreting something here????)

Here are pix: if I pulled the Felpro gaskets, the intake would drop about .090" but still have a gap from the bottom of the intake to the china wall. OP, do you have nice even gaps at both sides like these? (I am guessing not....) And are the bolt holes to the heads lining up like the 3rd pix? This is with the intake just set on the heads and intake gaskets, heads torqued but no bolts or torquing on the intake.
