This is possible?

Possible, yes.

I would not advise it at all. I can't imagine once the pressure is released off the HG's, that when you torqued each back down, that you would get a good seal and/or compromise the HG's.

To get to that piont you would have to have the intake and valve covers off. Four more bolts at the Y pipe and the head are off.

On the mgb you just go back around in sequence at the last torque value not starting over from scratch.

I found after a few heat cycles that all were just a touch below spec

Misunderstanding...

Remove a bolt...replace it with a stud, washer and nut. Go to the next bolt, replace it with a stud, washer and nut. Again, wasn't removing the exhaust manifolds or any of the other stuff.

Yes, it does work.

Right, I knew what you meant. I just didn't know that *that* was possible without having adverse effects on the gasket.

From what I've read in previous posts I think you're going to have a tough time un-torquing the center head bolts. You need to pull the bolts out in sequence (starting with the end bolts) in order to alleviate stress.

Just said it was possible. Think I may have even hair line fractured my thumb when one of the bolts on the driver's side came loose. I had to hold the socket on the bolt head while my neighbor applied torque via a 3/4" breaker bar with a 1" ID, 3' long piece of "cheater" pipe. Cheater smashed my thumb against the radiator support.

Again, HG never moved and I had 9 other bolts in place with just one at a time removed. I've combustion gas checked it; seems to be fine. Slowly torqued each @ 25-50-75...then final at 88 ft. lbs. Just felt better with ARP studs in there than those damn factory stretch bolts.

I'm about to get my head gaskets replaced on my 02 Kalahari with 225K on it for routine regular maintenance. I'd like to go with the ARP stud's but according to AB you aren't supposed to use the cheaper 124-4003 kit with the composite head gaskets.

What in the world is the difference between the 124-4003 & 157-4301 kit? I just want to make sure I just don't save $100.00 on the studs and then cause my head gaskets to go out prematurely.

Any info or input would be greatly appreciated.

I have not checked the # from phone.
But LR changed from 14 to 10 bolts in the later head. If one # is for LR and the other is for a 215 Buick that could the difference.
The Buick by the way fits and you get 8 more studs and are cheaper go figure.
