What's the best anti seize/lube to assist head bolts and studs when refitting?

[BartonStag]

Hi all,
Ready for cylinder head refit now. Any thoughts on what's the best anti seize (IE copperslip, maybe engine assembly grease?) to put on the studs and bolts please? Hopefully will never need splitting again ......but!! I'd like to try and avoid the sorry saga of when i tried to remove them this last time if possible!!
Thanks

Having been educated against using stuff like copper slip , I started to use this…. Seems good.

Triumph torque figures are dry fitted so don't get any on the threads of the studs or nuts. The actual torque figures applied will increase (it removes the sticking and friction between the threads) in the area of 20% if you do, depending upon fastenings employed or condition of threads in the block it can take you close to material limits.
