If the valve action is not as aggressive at opening and closing, the springs won't be required to do as much work to control 'em. There's not gonna be MUCH difference but, "the straw that broke the camel's back" may not show up.

My combo is scj heads and a460 rockers the cam i got from scotty j says .020 hot lash what should they be set cold for breakin ?

4 less cold for aluminum heads and 4 more cold for iron heads. With aluminum heads the lash opens up and with iron it closes when they get to temp.
