cylinder stud ?
 

engine rebuild time!
engine froze up over the winter.
luckily only one p+c was damaged.
already found a replacement (thanks tom b).
now the ultimate question.
i am using our hosts book to guide my rebuild.
he's pretty adamant about putting in case savers during a rebuild.
my studs look great, no piulling at all.
engine (72 E) has about 100K may have had a top end rebuild in the past.
should i pull the studs and have the case savers installed?
or just leave well enough alone?
i don't plan any wild mods just a stock rebuild.
advice and opinions welcome.

Without any experience with the older cases, folks seem pretty consistent in their recommendation that they should get inserts. From what I've read, the mag cases are particularly vulnerable to weakening due to the heat cycling of the engine over time. It might seem counterintuitive, but my machinist says that with inserts the case is actually BETTER than new, and that it is a superior design not a lesser repair.

For the money, I think it would be cheap insurance. You don't want to build the engine and save a few hundred bucks on the foundation of the build only to find that the heat cycles soon weaken the metal. This is a strength of materials issue.

Good luck!
