the head decked 50 thousandths
he only seated the intakes 30-35 thousandths Meaning, sunk the seats .030"?
I am concerned about intake valve to piston clearance
Yes, it's going to be tight. It won't be the difference between the old and new lift because the overlap lift is very different.
the valves were tipped Meaning he shortened the stem tips by .030" also?
The new lift alone requires a minor adjustment: the valve-side lever must begin higher by 1/2 the lift change, or about .025" on the intakes. This is much less (duh, typo1) than any lash cap thickness, which begin at about .050".
Shimming the rocker stands is going the wrong way.
The mill alone requires no adjustment, unless you run out of pushrod adjustment, and then the fix is a new pushrod.
If the valves have been sunk by .030", deduct that amount from the height correction above. If the stems are shorter, that adds to the correction.
As you see, some of these things cancel each other out, and some are small enough to work as-is.
Confirm questions above?
