FLASH,
Only the most restrictive of rules, cumulatively, in addition to the 6:5 payout in a SD game will give the house an overall advantage of slightly greater than 1.8% The Wizard of Odds House Edge calculator cites that an SD game paying 6:5, H17, nDAS, resplit to two hands only, double on 10-11 only, nRSA, and no LS will give the house a 1.8399% advantage. But Kasi is also right, the 1.4% is just for the 6:5 payout in and of itself.
