1) remove engien(not necacary but can make it a bit easier)
2) lossen & remove the 4 bolts on original head
3) pull head off away from the crank
4) be ready with you hand under the head to catch the pistion so it dosent crack
5)to remove piston from head you must remove these c-clip things. i had a hard time witht his and cant explain it so some one elese help here
6)once piston is removed take the wrist pin(that metal clynder that went through the piston and crank. and mesure it.
7)figer out if you got a 10 or 12mm wirst pin and order your head kit acordingly

to atach your new head kit revers steps 6-1

i do suppy a guide for removing and re fitting head kits with the kits i sell. all is pretty straight forward as long as you take your time and pay particular attention to the following; both mating surfaces [ case top and cylinder base ] must be as clean as possible, piston rings can break easy if not handled with care, piston pin c/clip retainers must be positioned into there reccessed area, piston is to be positioned the correct way on conrod.
