Just pulled the engine out of an 02 CBR954RR and putting it in a donor bike, oil had coolant in it. (Could it be from lying on its side for an extended amount of time?) paying a buddy of mine to replace the head gasket just in case. What will I need other than gasket and head bolts? I do everything but actual engine work. Trying to go cheap with it and use as many good parts as possible, zero shavings in the oil.

Also engine ran good on all four before I pulled it.
