Mk1 "HA" 895 cylinder heads - part numbers/ valve size help.

Recommended Posts

Hi all,

 

Would anyone be able to help clarify the cylinder head part numbers for the mk1 HA engine (895cc) with water heated manifolds?

 

Mine's a '78 with part number 052 103 373C, but I'm being offered a one with part number 052 103 373A. Is there a significant differences between these heads?

 

I gather that most of the early heads are all the same (camshafts aside), but I'm being told the inlet valve diameter for 052 103 373A is 34mm whereas my current one is 32mm. Does anyone know if the one I'm being offered is suitable?

Thanks.

 

I've tried a few of the online catalogues but they don't list the bare head numbers, unfortunately. If they list any numbers at all (many entries are just blank or marked 'unavailable') they are for the exchange units with camshafts etc, which I don't have for the head I'm buying. 

 

Online advice elsewhere is a bit contradictory, so I'm being a bit cautious!
