Default Re: Big Valves and porting?

Do larger valves and porting increase flow? Yes, but very limited.

The cylinder head chamber design has more of an effect on the flow.
As previously stated, there are many other factors, manifold, carb and exhaust all contribute.

It will take a stout bottom end to utilize all of the HP possible, but that is another topic.
