<VV> 65 or 66 RB engine

[hallgrenn at aol.com]

I wanted to check to see if an RB engine T1217RB is a '65 or '66.  It was sold to me years ago by one of our respected Corvair experts as a '66, but it had the early 140 heads (small diameter top cover bolts mixed with the big ones).  I don't believe there is any way to tell if it is a '65 model of '66 model RB, but I thought I'd throw it out for discussion.  I have no problems with my purchase as I believed it was a '65 when I bought it even though it was represented as a '66 (maybe the heads were swapped), but I've always wondered if there was any difference that would tell one year from the other besides the top cover to head bolts.
