Need help Identifying 1970 TA heads

I would appreciate if someone could give a good detail description of identifying TA heads--pictures of the offset would be most appreciated or a web site which would show me this info.

Or...

you can not ID them just by the casting number ...you need to look for the offset pushrod holes...

you dont know how many people think they have a set of TA heads just because of the casting number..

Tony---you are so right about the casting # being TA's but your pictures prove them not to be.

Thanks
