Stuck valve guide

I have a 327 inline that’s in a 52 200 touring sedan . It’s engine was rebuilt . Since the rebuild by a mechanic who perhaps didn’t do it right , I’ve had problems blowing head gaskets repeatedly . This last time I started thinking it was because of a stuck or sticky valve . Sure enough “ guided” by this concern the mechanic found a heavily worn guide # 5 exhaust valve from the back , and a bent valve .
Great mystery problem solved !
But can’t get the guide out
He said it’s stuck said could only get it to move 1/4”
Is that common ? Is that a engine killer ?any extraction wisdom?
