Even if the 14 cracks, if your machinist knows what he's doing they can be welded. I do it all the time and there are members on this forum that are driving around with my welded heads for years.

For what it's worth, it's not a matter of preservation - the head WILL crack and has most likely already started. The expansion tank cap in PROPER working order and preventing overheating will postpone your head removal. I think the lowest mileage 603 I've pulled apart had 27k on it, and it was already cracking at the prechamber.
