Maybe more proper way is to modify grep, allowing it to take filelist
from file, including stdin? Then we can do something like:

find . -name '*.h' | grep --filelist=- pattern
or even
find . -name '*.h' -print0 | grep --filelist0=- pattern

Find will find, grep will grep, perfomace will be good :-)
