Need help removing Flatty head studs.

[sedan_dad]

I've been at these for two days.The nuts came off easy enough.A couple of raps with a hammer loosened the head right up.I started soaking the studs with Kroil yesterday.Today I hit them with PB Blaster all day.I just broke a stud extractor on the first stud.I thought about dry ice and a "hot wrench".
Any input.
I really don't want to brake any studs.

My only advice is a good extractor and maybe some heat. But first make sure best you can the block is worth it. The last one I did had beautiful crack free decks so I spent about 4 hours pulling studs just to find the bottom end full of cracks a few days later. Sorry but you will break some.

my experience has been that patience works best. Keep adding the penetrating oil and keep tapping the studs with a hammer. It may take a week to loosen up 50+ years of rust.

I read on the fordbarn.com that one of the guys heats up the block and melts wax at the stud. The wax is drawn down into the threads and the stud can then be removed.

How about dry ice?Anyone try that?

PB/Kroil and heat. Heat gently and spray. The capillary action will suck the stuff deep.

Dont use a regular wrench either. An air impact works best. Set at a low torque to start and keep increasing while going both directions.

And yes you will probably still break a few.

If you have the time and materials then soak in molasses mix for a few weeks. That suff penetrates well but all oil and grease must be removed first.

We have pulled several studs outta the flathead block I have...all done with heat. Get the torch on the stud till its red...and then shoot some blaster on it....usually gets it off by the first or second try. Haven't had a broken stud yet doing it that way.

Invest in a good stud puller, like Snap on. that works concentrically with the studs.
The cheap ones that put your wrench over to the side exert way too much force in wrong directions. A good one is expensive, but you'll pay for the cheap one in blood and sweat as you work over 15 broken off studs.
