I will say this One More Time. Also I will type real slow so even those who are slow readers can follow it.
There is absolutely "NO" part of the human anatomy which touches the wood at the top of the heel. Therefore scraping wood off the top of the heel does nothing to alter the fit of the gun. The purpose of increasing the drop at the heel is in reality to lower the entire butt, thus changing how it fits the shoulder.
Scraping wood from the top of the butt will not do this as nothing fits there, you will only have less wood projecting at the top. Bending the stock down will alter this fit.
