I'm having major trouble getting to seal . I got the fond thick gaskets that are silver and they are all torque properly . Any idea if putting 2 on would help ? Allow more crushing of gasket material ?
Mine aren't great . They are bolted together still and sitting face down on kitchen table . They don't match up well at all .Biggest issue with them I have had is they got tweaked. I look at them with a straight edge across the runner faces and try to true them the best I can.

Also my studs into head keep leaking water . I've done them 3 times now with " loc tite" thread sealant and still water spraying through the threads
Good gasket - the silver thick ones , best ones and most expensive ones far as I can tell .Let's address a number of things that could help solve your issues.
I don't know what a "fond thick gasket" is. What brand and part number are we talking about?
Using two gaskets won't help at all and will make things worse, doubling your chances of a leak. If you don't have one, get a RemFlex gasket set for your intake/exhaust. They are expensive but worth it.
Are you following the torque pattern in the FSM (you do have one, yes?) to tighten down the manifolds? When I do a torque pattern, I do it in thirds. If it calls for 60 lbs on the bolt, I do the entire pattern at 20, then 40, then the final 60 lbs. The manifolds get very little torque, don't overdo these!
Are you using all the correct hardware, and are the special washers oriented properly?
If your intake is old, and the exhaust is new, it's likely they won't match up well. If the manifolds are all wonky to each other and not true/flat, no gasket on the planet is going to help you out. Best bet is to mount them together as close/true as possible using a straightedge, tighten them up, and then take them to a machine shop to get the mounting surfaces trued up. The guy that did mine used a gigantic belt sander to flatten and true the two to each other.
Others with more experience may jump in to help here, but I don't think Loc-Tite is the product you want to seal a stud going into a water passage. I used Permatex 2 on one head, and The Right Stuff black on the other. Neither one leaked a drop. Did you chase all the threads before assembling everything? You need to make sure all the old crud is out of the threaded holes in the head before assembling the new studs - and everything else.
I first used the black permetexk stuff I use in my industry as a steam fitter . That leaked . Guy I'm hear said to remove snd get lock tight brand " thread sealant " so I did that - twice actually . They still leak profusely .Let's address a number of things that could help solve your issues.

Yes using all new factory hardware , and triangle washers and brass ones to where requiredLet's address a number of things that could help solve your issues.

leave the two manifolds bolted together and take to a machine shop ?
I am using these . They're leaking by stillHalfafish is right; it is very much worth your while to not mess around with anything except the good gaskets for the manifolds-to-head and intake-to-exhaust junctions.

? I keep saying I have the best gaskets they make guys. I'm taking the manikfos off tomorrow ans we'll use straight edge and see how bad they are as far as being true to each otherDo this + the good gaskets and you'll be leak free.
