Engine model in my Massey Harris 444

[FarmerHR]

We have a Massey Harris 444 gas tractor. The serial number is 705xx.
Where do I find the model number of the engine ? It is a four cylinder with a 4.000 inch bore made by Continental.
I need to order some parts and I want to make sure I give the correct engine model. I believe it is the original engine.
Thank you for any help you can give me.

Gas is H277, diesel is HD277. Should be stamped on the upper right side of block, front or rear pad.
