Im am doing the top end myself on my 2004 450 for the first time and I have a few questions for anyone who can help.
- what is the torque for the 4 head bolts?
-are there any other torques I need to know? (cam perch bolts, etc)
-do the rings go on any special way like the old two strokes?
-what are the valve clearances for setting the valves?
If youve done this before and know of more things I may need to know, please fill me in! Im on my 3rd motor in about 1 year, so I figured why not give it a shot myself...whats the worst that can happen...4 motors in a year!

Thanks in advance!
