increasing the lash in mine (i.e. making the cam look smaller to the motor) made a bunch more power everywhere.
That was with ex manifolds, correct?
The increased lash making more power if there were headers installed on the motor may or may not have played out the same.
Yes.
Correct, That is why I said that with a smaller cam in your example, the manifold motor's power might go up, and in the header application it might go down. But maybe not.
