Hoping the throw the motor back together quick and easy, so hoping there's some wisdom that I want on the board here. 

Would like to know if a Schrick-ish 292 will go in without additional machine work to clear the pistons.

It's an E21 but will have the 9:1 pistons from an e30 M10, figure stock thickness head gasket, if need be I have an adjustable cam sprocket (the one from IE).

Anybody here run a 292 in a 1.8 on a throw it in and forget about it basis?

I can't say anything definitively, but I've never heard of any issues with a 292 and higher compression pistons. The only thing might be if the dome shape is not matched to the head, or if you've got larger that stock valves. I run a 300 Motorsport cam with ~9:0 pistons and have zero issues, and I've heard of lots of others with up to a 304 and stock or other factory pistons with no interference problems. I've always had the impression that there was a fair bit of leeway in the M10 for more lift/duration until you start getting into track builds (316 or 324 cams, 10:1 pistons, etc.).
