Default L92 Heads, Which Casting # is Better?

Not sure where to post this, so i put it in external and internal.......

I have been looking at some L92 heads for sale, and i was wondering which casting # is better? The 823 casting, or the The 0821 casting? I have an opportunity to get my hands on some for a very reasonable price.

Also, not that i would personally do it, but would it be acceptable to run two different casting heads? Say, one 823 and one 0821?

Thanks!

Without a doubt the 823 casting is better. Ports are finished better and the exhaust ports are noticeably bigger.

823 is the normal head
