I need to pull the engine but not sure the best place to attache the chain or puller plate to get best lift balance and most importantly NOT break any thing. Ideas please.

 

Dave, I would choose two head bolts at opposite ends and opposite side of the head. Remove the head bolts and install through a chain length suitable size and length. I've never had any kind of puller plate and used this method with success on different engine sizes and configurations.
Now, the question. I am sure you're just doing this to detail the engine and compartment, right?

 

Ray the rear main seal is leaking very badly. Used a quart of oil on a 25 mile drive. It is made of wood!! The hardest part was finding a replacement. The engine has an oil slinger and to go to a modern seal I would need to change the crank. The current wood one lasted 73,000 miles and 40 years of being in a barn on blocks so maybe it is a decent system.

 

Before you use the head bolts, take one loose and see how how much it threads into the block. The only potential problem with Ray's method is that the heavier the chain you use (which is good), the fewer threads will be into the block. I have to believe the Stude guys can tell you what works.

 

Ross I tried to get an answer from them but they just don't respond the way everyone on the best forum (this one of course) does. I was just worried I would crack the head or as you say it might not go in far enough to hold. I was thinking I may use a strap all the way around the engine both front and back but wasn't sure if it be to unsteady side to side.

 

If you have any concerns about thread contact, get longer bolts and use a flat washer on the chain links. Put the end chain links in a vise and make them round. A smaller chain works fine. I forget if I used 1/4" or 3/8" chain.

 

Ray I think that is the safest way to go. I have the chains and a couple of different types of 'D' clips that screw shut. Thanks to both you and Ross it is very reassuring to have your input. Thanks
