Longer push rods ?

Once you get your lift in the ballpark, try changing pushrod lengths and rotating the complete assy. minus plugs. You'll be suprised. And the more valvespring pressure you use, the bigger the difference will be.

There is only one push rod length that will maximize the area under the curve that was ground into the camshaft. You can shift characteristics of the camshaft by changing the length of the pushrod. You can shift the area under the curve, but it will REDUCE the total area under the curve and it will change the torque to rotate it. If you shift the characteristic by changing the length and the engine likes it, then you have an opportunity to regrind and make additional gains. What you would really want is to maximize the amount of power and reduce the engine rotation friction to a minimum. If you do that, you WILL get a double whammy on power gain.
