M50 '92 Valve Job - Any advice?

I may have bent a valve at my last track event. I've got a 92 325is 279,000 miles. The compression on #2 cylinder is 0! The others are all 210-220 ft/lb The car still runs OK, but you can tell there is a problem. No smoke at all, but the exhaust smells rich.

Has anyone done a valve job on this head and had anything interesting come up?

Is there anything I should have done when I get the head worked? I was planning to replace the valves in the bad cylinder, but if the others look good I was just going to have them cleaned up. I will replace the timing chain(s) regardless.

Any performance mods I should consider? Better springs, etc.

I will pull the head myself, but I am going to have someone do the work to it.

Any advice would be appreciated.

Thanks
Mark

you cant adjust the valves on an e36, its not like an e30. It has hydraulic lifters.

Doh, yep meant PSI. Torque is not the issue here.

Yes, I don't think I have adjustable lifters.

Any thoughts on gasket brands. I've seen sets sold for the entire job, including valve cover etc. at the usual bmw online parts sites. Anyone had experience with those?

New Head bolts, not a bad idea either.

Thanks
Mark

I got a bottom end kit with all of the gaskets. It was victor reinz brand, the motor is not back together as the pistons need replacing, but the kit seems to be fine.
