Has anyone tried this? it looks like a loss of compression by using the 04 piston. But DAMN tha sucker is lighter! How much is needed to be milled of of a stock 2000 head to get a nominal amount of compression increase? .030"? I as thinking .020 off of the block and .020" off of the head would be a good starting point. Mmmmmm now which cam to choose?

while you're in there, see if the 04's titanium valves will work...

Nope. The 04 has 4.5 mm stems. The 2000 has 4.0mm. I'm not sure if someone was to replace the valve guides with 04 guides?.....Not sure if the outside dimensions are the same. That would probaby cost another (enter big value here) of money that I was looking to not spend.
