helicoil in heads

Steve the 915 casting number is used for the 1970 TA head and non TA heads made from 70-72 (don't ask me why Ma Mopar used the same # for different heads) but the TA heads are different because they have offset intake pushrods to allow more intake port opening. The other 915 heads are the same casting design as any other small block LA head. I noticed yours have the offset pushrods and rockers which makes them the TA heads.

Your a lucky man. The TA heads are worth a small fortune.

Thats good info. I never really looked into what they were too much. I also haven't seen too many other heads or the rockers to notice a difference in mine.

And you know what else makes me lucky?! They were given to me.

I took another picture, you can see 360 cast into the head on the opposite end of the casting number. What is that there for?
