If you haven't decided to remove the intake manifold and oil pan to retrieve all the loose pieces, are you feeling really lucky
Do you really want to take a chance of one of those pieces falling in between the cam and lifters or the in between the cam and block
I broke a inner valve spring on one of my old bracket motors years ago, it spit the pushrod out and the roller lifter, I took the intake and valley pan off and replace that pushrod, valve spring and that set of lifters and ran it for several more races before selling the car to a guy who had to absolutely have it right then. He raced it for over six months one to two times a month and ended up spinning a rod bearing after loosing the oil pressure and not noticing for two runs
A piece of that broken valve spring tip was lodged into the oil pump locking it up
Murphy loves messing with us drag racers, don't you know
Fix it now properly before running it again
