Reply to "Port Plates.."

On the intake side, I would use "port stuffers" in the head, if I were runnng an intake manifold, like the Parker Funnel web, that was designed to be used with stuffers, because it is an engineered system.

I would NOT use intake port stuffers with a manifold that was designed for a full size port. You are second guessing the designer at that point.

Make sense?

The Parker Funnel Web, by the way, is possibly the best intake ever designed for the 351C 4V iron heads, in terms of sheer bhp capability.

On the exhaust side, I've seen guys braze in the bottom of the exhaust port, run MPG stingers in place of brazing AND I've seen guys run the ports as is, in all cases the ports were extensively ported inside. I've seen impressive bhp numbers with heads in all 3 configurations. In fact, guys are getting better bhp numbers today, running the exhaust ports as is, than they did 20 years ago, running the high rise exhaust port plates.

There are knowledgable Cleveland engine builders still running the exhausts both ways (stuffed or unstuffed), so no consensus there. My take is, if you can build the power without modification, don't modify.

Of course with all the alloy head choices there are today, I see no reason to stress out over how to modify the iron heads.
