912 Oil Return Tubes

I am replacing the oil return tubes on a cylinder head. I have successfully removed the old ones as per the manual and have purchased two new ones. However, the manual states the new ones should be pushed and twisted into place but both are drop fits. I have measured the new oil return tubes along with an original fitted to another head with a micrometer and the new ones are about 0.1mm smaller in diameter. Is this normal or do the ends of the new return tubes need to be flared?
