Taking the weight off of the nose from the (nearly) highest point of the engine is second only to removing unsprung and or rotating mass. If you're going to feel it anywhere, you'll feel it there.

Aside from the performance improvements over stock low compression heads, the weight reduction alone is incredibly valuable in making your car a better driver all around.

Also, be sure to run aluminum intake and water pump to save a bunch more weight...if you haven't already gone that way.
