My brother blew up his 05 450. So we are stuck trying to figure out what to do. What would you guys do for parts for a complete top and bottom rebuild? I want to know about a crank kit, piston, head, valves, etc. Also, we were told that the head is toast, so are there after market heads or do you have info on where to get a new one, or reliable used? Thanks for your help.

my crank/wrist pin seized on a '06...i got a after market crank, and a JE high comp. piston, the cylinder was egg shaped by about 3~5 thousand's of an inch which is way to far outta spec so i got a cylinder also, besides that stuff i got the oil mod kit, and it's ran like a champ since...just make sure you change your oil alot.
