New Small Block Stroker Engine Noise

The top gasket is the FelPro 1413 which is recommended by Edelbrock. The heads are port matched to this gasket. The bottom gasket is what is supplied by TTI. The headers match the TTI gasket. You can see the headers won't seal on the outside ports. This is like running 340 manifold on magnum heads, they just won't seal. This could very well be what is making all the noise. Now how do I resolve the issue??
