2.5 24 valve head

Here you go. You can see my new ITB inlet manifold project which I never got to fruition, might need to pic it back up

Thanks Leigh.
I'm just juggling screenshot now to compare the two.

Look identical to me?
Can anyone confirm the 3.0 and 2.5 heads are the same?
Anyhow, looks like you might need to hang on to this Leigh? Or would you be willing to part with it?

I've got the two side by side in my garage too. I've had a look in the past and the only difference I can see is the port and valve size for the larger engine. When I get home this afternoon I can have a better look at both. All the cam covers from various 24v engines are interchangeable, the later ones have a breather outlet on both cam covers rather than just one.

Here you go, a couple more pictures for comparison. The 2.5 head is the one on the left of the first picture or on the top of the following pictures, the other is a 3 (actually 3.2, but they’re the same). You can see the manufacture dates in the first picture. Valve sizes for the 2.5 are 29mm in, 25mm exh, 3 litre is 31mm in and 26mm exh. Ports are visibly bigger too.

I need it at the moment but might part with it in a bit. I shouldn't have replied to your post, I forgot about my inlet project

What are you going to do with it? You can but a 2.5L head on ebay for about ?70
