2012 TE310 Cam Replacement

Have a customers 2012 TE310 brought in for the start issues.
Had cam out to reset cam tolerances tighter to help the decomp.
Noticed the cam was ground wrong as in .010 difference from one side to the other. Both lobes only way this could happen is the cam grinding machine stone was set on an angle not square to the cam lobe.
Problem is ordered new cam and got what they say is the superseded new on old part #8000H6057
new # is 8538407 been told this is BMW #. New cam looks similar but are some differences grind is different with some ramp configuration and some duration changes ok can live with that but there are no timing marks only 1 dot on a tooth that does not align with anything close. The H logo and part# is only thing printed on it.
Looking for anyone who has put one of these in.
Of course no help from H they don't have a clue and could care less.
This could be the magic bullet if it works. I doubt this is the only badly ground out there.
Have talked to all the good Husky dealers that are left and none have seen this.

I would suggest doing a degree check of the OEM cam and then use that to position the new cam. I did that a lot in autos in the past when I did not have a good set of spec's to work from.

Totally wrong cam won't even go in.
jumped the gun on this one.

Exhaust cam?

I have a set from a 2010 TE250 that was in a fire.

Magnesium cover melted and the aluminum head is toast but I bet the cams would be okay once cleaned.

Walnut shell blasted or something.

I could take a look at them tonite. Journals should be okay.

You can have them.
