Exhaust crossover - question regarding flow

Have an interesting technique, tool or just anything related to porting? Post it here . . . please no bashing anyone for the model of engine they are working, we're here to share ideas . . .

What affect does the exhaust cross over have on the flow of the port? Being more specific I am working on a set of heads for a ford 460 casting # D3VE. One port in each head has the exhaust crossover plumbed into the wall of the bowl creating a large open area on the long side. I do not need the exhaust crossover warm-up feature and will be block at the manifold. I am considering filling in the hole in the wall but would like to know if this hole affects the flow of the port before going to the extra work.

Thanks for the reply,
You just saved me a bunch of needless work. You even answered my underlying question of the exhaust gas contaminating the fuel charge during overlap. I was saving that one for further posts. Do you also read minds :laugh:
