Meth Addicts and Compression Drop

Hey Guys,

I'm running a stage 2(.5?) maxPSI kit with a PT-6870 and getting ready for a grudge race next spring against a friend of mine. I wanted to get people's personal experience from two power adders.

1. Meth kits: I hear mixed stories with meth kits on the s54 FI world, they work great on my rotaries but obviously apples to oranges. What did you like, not like, and what problems occurred from running meth?

2. Dropping compression: I'd rather not build the bottom end just yet and looking into installing a thicker head gasket but once again it doesn't seem like there's much info out there on that. I have one or two shops that are experienced in other bmw platforms but want to hear more info on people's experiences from dropping compression with a head gasket. Were knock values affected? Any issues with installing them, or sealing? etc?

EDIT: Just was made aware of a cut ring gasket option,
Any thoughts on this as well?

I would appreciate any info or advice. This guy has been running his mouth for awhile now and although I know my current race gas mode is plenty to beat him, he's talked enough trash that I'm looking to humiliate him. Help me out guys
