I have a L3710D tractor, engine is a V1903, ser #YW0008.
The repair manual shows that up to December 1993 took a cylinder head model N-TVCS combustion chamber. I believe a customer before me put on a later model, from January 1994 and newer, model E-TVCS. My question is, are they interchangeable other than the later model one has better emissions than the early, or will the engine act like it's running very rich with the later model head on an early model engine and block.
Thank you for any help you can give.
