Seems sort of a waste with no teardown, just do what you want and make it look "stock" if they ever take the valve cover off.

IHRA has P&G'd my motor. And they were a lot closer to the real cubic inches than NHRA. IHRA was within half a cubic inch of what it is.

I've always declared the right cubic inches. But sometimes I've been pumped and come out 6 or 7 cubes low. To me that could be over 100 pounds.
