As Wil said, the weak link will be the female threads in the block, stronger bolts won't do much unless there's more thread engagement. It might also be worth considering the benefits of the waisted head studs - thinner shafts mean better elasticity relative to the clamping force.

I’ve normally found it’s the thread in the gearbox casing that strip from the casing, even then there is ‘just’ enough metal to helicol them back to the correct size.

Rebuilding my S block at the moment and that had already had 5/16 thread holes when I bought it. The block had been used for racing in Oz at some point and I expect that is why the modification was done.

 

I see MED sell a copper gasket. Is it worth doing this or is the standard gasket up to the job.

 

Thanks Dave
