Intake manifold doesn't fit right

Im installing some new gaskets on my 318. I put the intake manifold on and it appears that 2 intake ports are not being covered 100% by the intake manifold.

I don't get it, I checked all the casting numbers on everything and it should all work with each other just fine.

engine block
2536030 67-75 la block 318

heads

manifold

thanks
