I have never had this issue before. I have new AMC heads and new EMW 96mm clyinders. I assembled the longblock to check valve train geometry. I need to send my heads off to get the valve guide bosses cut however I cannot remove the jugs from the heads. I do not want to break any fins so I haven't tried much other than muscle.
Any ideas? Attached image(s)

Uh, something is seriously wrong. I think amc heads are 1.7 bus castings that were modified for the 2 litre. You might have to open up the registers for the 96mm cylinders to fit into.Might try air pressure thru the plug holes to pop them loose.

The strange thing is that prior to putting the engine together, I put one of the jugs in the head to make sure it fit properly. There was a very precise fit, I did not difficulty putting the jug into the head without any major force. I think that there is just a super precise fit. I will try to heating them a bit later today. |

In that case, I would rubber mallet them into the head as they are likely cocked just a little. This ought to free them up. Then heat, beat, repeat. I would not use a tap. Heat should give you the clearance you need and a rubber mallet is the persuasion. Always hit the cylinder parallel to the fins (duh). |

Will get this fixed soon so I don't have that issue again. |
