i am trying to take the heab off of a 1973 220 with a inline 4 cylinder 2.2 liter motor. i have all of the head bolts out and i cannot take the head off because the timing chain guide is restricting me from taking the head off. i look in my manual and there is a bearing bolt that holds the guide in place to the block. My question is how do you get that bearing bolt out of there to take the tiiming chain guide off to get the head off. Is it a reverse thread bolt or do so need a special tool to slide it out.
