Help with head ID

I have a set of heads that I found as I am cleaning and I dont have any use for these. I remember buying them just before I found the heads I used in my stroker build. I dont remember what year heads they are or what they came off of. They are not 2.02 valves. The exhaust ports are the rounded ones. Was wondering if anyone can tell me anything about them by the numbers on the casting. 8947041, with an L14 8 under that number on the one head an A80 70 above the other head. Also they both appear to have a T stamped into the head. Something tells me they are from 66 - 67 327 motor but I just cant be sure. I plan on selling these once I figure out what year and what they were on. Thanks for any help you can give me. http://s1014.photobucket.com/user/rod7515/library/dodge%20parts/vette%20parts%20for%20sale There is a link to look at these heads. I still dont have a bar to paste them into the thread so you will have to copy and paste. Sorry Rodney

when you say accessory holes are you referring for Alt and PS ? These have the 3 bolt holes on the one end and only one bolt hole on the other end so it will make a difference how they are mounted for use. Thanks joel, now I cant wait to hear more! They were supposed to be a good set but I just cant remember. Im just glad I remember how to get home each day and thats a chore at my age! Rodney

Yes....the threaded holes on the ends of the heads. But..actually, it doesn't matter which side of the engine the head goes on...the three hole will still be on one side and the single hole will be on the other side..think aboot it....
