Do Schumacher slant six to 340 motor mounts raise engine?

It would help a lot if the OP posted more info and pics of what he has instead of making everyone guess. Kim
What is there to guess about? I put Slant Six to 340 Schumacher motor mounts with biscuits on my 340 with six cylinder. K frame set the motor in and the head won’t close. No guesswork there, sir.
