No. Its shimmed for 30% around. You need to reduce the head shims to give you 0.3mm head clearance.
For running in preheat the engine to 160 deg f and make sure you keep the temp up for the first 2 tanks on idle.
I wouldnt reccommend the WOT method (if you dont know what it is dont bother) This stresses the engine too much
