To seal, or not to seal

[Omen]

That is the question. (apologies to Bill Shakespeare)
TV8 engine. Left hand bank does not have gaskets between the exhaust manifold and the head. I'm told that is the way it comes out of the factory. Right hand bank has gaskets that at least one has blown.
So undid all the retaining bolts with huge difficulty, as don't have the time/inclination to remove either the head or the engine, the manifold moves away from the head enough to get rid of the old (powdered) gaskets. Install new ones and do up the bolts. BUT not being able to get a torque wrench in can't get the bolts done up enough.
So I do I seal with gun gum/fire gum whatever to take up the slack left by the non torqued bolts. ?? Or find some way of tightening the nuts ?

I've replaced the bolts with cap heads and ground the heads where necessary to allow better clearances (I've a stainless system fitted). Using an Allen key drive socket I've managed to tighten up by hand to about the correct torque when compared to those I could get a torque wrench on.

it's all done by feel, I mean how on earth are you supposed to get a TQ on all those bolts?? just dont overtighten and strip some threads!

Well re tightened all of them again, but still blowing.
The gaskets are quite thin, so think will try doubling up on the gaskets, see what happens then.
Be back underneath this afternoon !!

Removed them on Tuesday, replaced them today. Did a bit more cleaning up in between.
Thought occurred to try and tighten them like head bolts, or wheel nuts, ie opposites. So nipped them all up initially,nthen gradually tightened.
Seemed to work, have a non blowing exhaust now.
