This spare head came with my Miata based Locost.  Based on the rest of the car I assume it is for a 1.8 BP, but which one? I know there are a few variants, some of which are more desirable than others.  It appears in fine shape, just used.  I think the Locost has a freshened head from Flyin Miata on it, so this is probably the original, but I have no idea.

Excellent, thanks!  Any idea what is is worth?  Trying to clear things out for a move this fall.

It's a BP05 head, which is decent. (It's not a BP4W, unfortunately.) 

Probably worth a couple hundred on eBay?

I would possible be interested in this if you're looking to sell it!

In reply to Hoppps :

If you need two, I have a quite nice and upgraded BP05 sitting on the shelf. I'm switching one of my engines over to a BP4W top end.
