Oil return line

I'm installing the baffles on my IO-320 Lycoming Thunderbolt engine and was wondering if I can remove the oil return line and plug the openings instead of drilling out the baffles? Installing a Catto 3 blade prop so no prop governor. Thanks for the help. Dave

If your referring to the prop governor oil return line yes. Be sure to cork the crankshaft as well if your switching to a FP setup
