Default Petter AVA 1 Cylinder Head

Just bought my first diesel,a Petter AVA 1. Will anyone tell me if this is the correct head for a series 1 or series 2 as it is different to the manual I downloaded. Secondly can anyone give me a date for serial 3136169S and as it was rebored etc according to the plate would this be the actual engine or renumbered when reconditioned?
Thank you.

Looks like a series 2 head. the Series 1 has a horizontal injector.

There are some variances, especially around the changeover from series 1 to series 2, but that does look like S2

Thank you Paul. At least all the parts will go together then.

If you email Jim Perkins he will be able to date your engine and confirm the head type.

Agree that the pictured head looks like a series 2 item. If you are unsure what series your engine is, with the head off the series one has a flat top piston as it is indirect injection. As the series two is direct injection the piston on your engine should have a hemispherical combustion bowl in its crown..

Thank you Dan. With the piston shape it is definitely a series 2

Had an answer back from Jim Perkins saying that it is recorded as an exchange unit of March 1958. Also that is was originally a series 1. Probably explains the head and the fact that it has a series 2 piston. Thank you all for your help.
