Well BenzMac, every machine shop will "say" they can. In your expertise, how would you choose? I'm not sure what " blowing a valve" means, and I've been in the machine shop business for a long time. If you are referring to the head of the valve parting company with the valve stem, that is not likely to happen because of mileage. If you are referring to burning the valve, that is also not mileage related. If you do replace parts, I would buy the valves from MBZ, not the aftermarket. I've noticed many people in the Mercedes Benz community, have misconceptions about what the terms OE, OEM, etc, actually mean.

i suggest checking with mike at metric motors to see how much you can mill.

but personally if it were mine, i would just check for straightness skim for a good seal and put it back together, unless things looked worn enough to warrent replacing parts. a good three angle valve job if mileage warrents it too. you dont say how many miles, but i am guessing it doesnt have enough to warrent even a valve job.

do you know why it blew the gasket?

any modifications to increase power to a noticable degree will get expensive fast and that engine is already pretty good.

You're asking for trouble increasing the compression ratio on a C36. It's already high enough and the timing aggressive enough that this motor relies quite heavily on its knock sensors. When the underhood and therefore intake air temperature climbs on hot days, you will already get some ping on even the best fuel. The notion that AMG left some unlocked horsepower in this engine that's yours for a minimum amount of effort using old-time Chevy and Ford tricks is laughable. If you want a faster car, buy a faster car.
