do you then, as with the departure segments on a single engine failure after v1, level off at 400 feet wait for speed to reach flap retract speed, retract flap and continue your climb as per the missed approach instructions.??
I hope that your airline trains you better than your post suggests ...
If there is no terrain to consider (eg over water) most operators will have a standard delta height above the missed approach altitude/height at which one transitions to the cleanup. This may well vary according to whether you are AEO or OEI.
If there is terrain to consider, you need to have had someone run a sensible escape calculation .. otherwise, sooner or later, you will become a CFIT statistic ...
QRH etc., drills can wait until you sort out the intial terrain problems, I suggest .. no point doing a perfect securing of the engine as you fly into the mountain ..
