Take 10% of your block value, then reduce by 1/3 to account for mob armour. Multiply by 1.495 for stance/defiance. Divide by 6 to amortise the cooldown into threat/second. That's what the 4 piece T6 is worth.
The gorefiend gloves will almost certainly give you more of a threat boost. (And 2.4 badge legs are way better than T6 legs)
It gets 307 innate threat that SBV has no effect on, and a base damage that your SBV adds on to. With 4pc bonus, you get (430 + SBV)*1.10 for damage. You're still only adding 100 damage to your Shield Slams if you have 600 SBV (about 17TPS)
