Valve guide seals for 3.9 heads, early or later

I have 3.9 heads, question is are they the early or late ones which have the machined valve guide tops so I can fit the upgraded hooded type of seal.
The factory number is HRC2210 9E704 on the top in between the valve springs, the number on the end is ETC8622
Cheers Damian
 
Hi Damian,

From what I can see from your photo, the guides appear to be the later type. Just check and make sure that there is a step at the base of the guide as the valve spring is obscuring my view. The oil seal fits down over the top of the guide, sitting against the step and is flush with it once fitted.

Ron.
