Yes. You use the most lift the valve gear will tolerate. I can put any head on a flow bench and with enough pressure drop can cause the lift curve to drop.

I try and get all the flow loss out, but I no longer go berserk trying to find all of it. Most of it comes from using a valve that is too big for the port to feed.

Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
