Help with PPI on a 4.6 in San Jose

[chivas]

Hey!

New here but been with the Bimmer family for some time. I am in Houston, TX and the X5 4.6 I picked up on eBay is in San Jose (2003 BMW x5 4 6IS Sport Utility 4 Door 4 6L | eBay).

Anyone:
1: know of this 4.6? he had the whole top end and timing done. is that super OCD or was there something I should know about the 4.6 (familiar with the 4.4 but not the 4.6) that he's done I should red flag?

2: PPI (see, look for known problems) this for me? Buy you dinner/drinks/lap dance/hooker/blow/hooker&blow (not judging here, different strokes for different folks!)

very new to the X5 scene (want to know about E39 540's? PM me) and am excited to get back into a BMW.

Thanks!!
