engine?<
No - not normal and the head should go back to the rebuilder as the
clearances are possibly too tight, or there's a burr or dent on the
valve/guide thats catching and the valve stem might be scratched allowing
oil seepage (now or developing later), or there's a high spot which will
overheat and possibly cause the valve stem to fail.
Having said all that - and this is not good technical advice!!! - many
times if a valve sticks when new and frees again it will just work its way
in and be OK. But there's no guarantee - take it back to your rebuilder!
You've paid your money for a rebuild and this should not happen if it was
done correctly.
If I'd done this head and it happened to a customer of mine (God forbid!)
I'd want him to bring it back to me to be inspected and fixed
