Blocking exhaust crossover ports on intake?

blonzz · 09-03-2004, 04:49 PM

What is the best method for blocking off the exhaust crossover ports on a BBO Torker intake manifold?

I understand that just installing the supplied cast iron plugs will cause rattling and doesn't completly seal also.

Thanks,
John

I know this has nothing to do with your question, but did you know if you block off your crossover it makes your engine louder.

There has been a LOT of discussion on this subject over a ROP. You should check it out. There are apparently two kinds of material that can be used to fill the crossover, some people like one kind and others like the other kind (aluminum from old pistons and a zinc material from somebody like Mondello). I don't know as I havene't done it. I know that everyone that has used plugs agree that they will rattle with time. Whatever you do, good luck in the endeavour.
