Thank you for the guidance, gentlemen.  Good to interact with you all, again.

I'd hate to suggest free to a good home, but an unfinished head with unconventional chambers is, as Spank said, going to be a very hard sell indeed.

Maybe if you finished it and made it look all pretty with definitive chamber sizes it would be easier to value, but I wouldn't advocate spending big to do so.

That's going to be a tough sell. You'll probably want to go to turbobricks with that and ask around there.

I don't see that being something a lot of mini people are clambering for.

Hi All,

I've got one last 12G940 head on my shelf that I've been meaning to sell for years.  It's rebuilt, unleaded, mildly ported and three angle valve seat (if I recall correctly), dual springs, decked, rust-preventative coated, etc.  

Here's the rub:  Years ago, I reshaped the combustion chamber with the intent of using it on my turbo.  However, I didn't get my lines right, and ended up with something that looks more like a hemi head, with Mini beaks.  I don't recall what the chamber size ended up being, but I know that any lower compression could be mitigated with pistons.

Here's a pic of it when I was almost done with the grinding: https://imgur.com/a/NGC8B8z

With this in mind, what should I ask for it?
