Hi,




Have my engine in bits at the moment pending a rebuild.

Can someone please help me confirm if my heads are STI or not.
The cams are LHIN and L4EX, but with only one "groove" through the middle.

Any ideas?

 

This thing with the single or double groove in the cams is a bit of a red herring, if they are complete as out of the factory and have the small under bucket shims they are STI heads/cams.

 

Thanks for the info,

I will try and get another look today, Without removing the Cam, can i see these shims?! not exactly sure what I am looking for!

Thanks

 

I've had 2 identical sets to what you have and both had come from Version 4 Type R's.

 

Thanks. interesting. Seems to be a very grey art in the V3-4 heads. So many variables.

Here are some more pics i got today.

Thanks

 

v4 STi.......they have the correct valves and cam buckets

 

Thanks for the insight.
