There is only one way to tell which you have..............remove the head from the block.

HOW do you tell?

Short answer is to look at the shape of the combustion chamber.

Long answer is to use the SEARCH function on this website (use "early E88" as your search term_. This has been discussed a dozen times and people have attached pictures of the combustion chambers etc in those threads.

You can find the answers to a lot of common questions through the search function. (we tend to talk about this kind of stuff alot)

There's some pics of my shaved and ported E88 which is still open to debate as to whether it's early on not - probably not. Also Carl has attached an image of the early E88 chamber. Shame it's a head off job though!

I checked my head and i have the smooth head so its the late e88 that suks gonna changet, hope your is the first, but if you have driven early Zs dont you notice the diference? or is it because is chaved?

No idea how the car will drive with this head on it as I got it on Ebay. My Z's a '73 so it's probably go the late head on it anyway, certainly hasn't got any power that's for sure

You might want to consider shaving your current head, that would probably work out cheaper than sourcing an early E88 plus you won't have to mess about reseting all the lash pads and stuff! It wouldn't take much of a shave to get the chamber volume down to the early head spec I'm sure.

Cheers,
