So the L5P has some pretty stout heads compared to the older ones. I really want an L5P to play with

There is 1 difference noted with those studs.

I'm surprised they don't want an X pattern on the first 6 bolts

Okay, since no one spotted it yet in the pic above. Lets allow ARP confuse you a bit further.

Besides the torque values higher on the CA625+ what else ya see different?

The M8 is missing in the torque sequence on pre L5P, and two additional M8 fasteners on the L5P

Yea, low enough tq they probably figure it didn't matter

When I was at my pervious employer we would do 1 - 2 - 5 - 3 - 4 - 6 on the first set rather that the traditional "spiral" pattern.
