I assume they are not too much different than a 603, only x2 and
probably smaller. Yes, observe firing order. check for tdc by pushing
valve down to hit piston before you take the keepers off. take cams
off, wiring TC to sprockets. Mind the keys....
You can do 2 pistons at the same time (8 valves) then rotate 120º repeat.
Big problem is a valve spring compressor. THe MB special tool is
stupid expensive. (At least for 603) I never changed springs but did
replace valve seals in situ.

Anyone ever replace valve springs? I am putting some stiffer ones on
due to
high egp with the compound turbos. What is the preferred tool? I assume I
just rotate the piston to the top to prevent the valves from falling in.
