Start a thread about rebuild info i can look into it.

Willdo...I posted some pics from the initial teardown on the Overland thread, but should probably start an M62 rebuild thread so as not to hijack the overland posts.
So far the motor looks great, especially the bores. A little polishing in them is all I see, but no scoring of any sort that I can feel with my finger/nail. I'm thinking it is most likely then that the low compression I was seeing in two cylinders is from rings or valves. I'll put new rings in it, and lap the valves as part of the process.
I've decided to put 4.6 cams into my heads and build what will essentially be a 4.4 with the 4.6 top end. I'm thinking that 80 or 90% of the 4.6's added HP comes from the heads anyway and putting the rebuild motor into something like an E36 will make for a nice project and a monster when it is done. Maybe 320-330ish HP?
The only difference between the 4.4 and 4.6 heads are the cams and the springs. I've found and bought a set of 4.6 cams, thanks to a forum member, and am looking for a set of 4.6, or aftermarket springs without having to buy the heads too (since mine are in good shape).
New 4.6 springs are available from BMW, but aren't cheap when multiplied by 32. I have one spring on order, along with the retainers, seal and locks so that I can weigh and measure it all, and then try to find a similar and cheaper alternative that will work.
I'm expecting to need new bearings on the crank, at a minimum.
