Intake Alignment

I'm just about to bolt up an RPM Airgap intake on my fresh 340 build with RHS heads and noticed something. When I set the intake on with no gasket and bolt it to one side to measure the other side, I've noticed the gap isn't square (i.e. there is about a 10 thou difference in the intake/head surface gap from in front of the front intake runner to behind the rear intake runner.

Is this tolerable, or will this cause sealing issues?
