I looked here for a while and did not find anyone posting them, I apologize in advance if this was already covered in another thread
What are the intake and exhaust valve angles for the M-8?

The valve stem is at a 45° angle to the deck? Wow

So I misread, now you know the valve face angle and seat angles.  WOW!

Not sure how i pissed in your cornflakes, don't care much either; I thought you posted another reason for me to hate the M8.

You didn't, you don't bother me at all. But obviously I interpreted the question wrong by my typing the multiple angels as a responce.

I guess I could have been more clear in the OP.
I am looking for the valve stem angles off the center line of the bore.

Are they the same angles as the TC and Evo?

Twincam B2, 26° and 30°, 2 pair sample.

Thanks for the first hand info.
I was referring to stock factory TC and Evo heads. Some SE and CVO heads have long had different angles as well as some aftermarket performance parts.
