if you're looking for DD reliability I'd strongly advise stay to the low end of your power goals. 350 hp is still more than double the stock output! The higher you push the more things are going to break.
Oh and with "Great Power comes Great Cooling Responsibility!" The stock cooling system was designed to handle the thermal load of the stock engine, by doubling the output you're going to have a much higher heat load, even ignoring engine bay ambient temps from the space heater like turbine housing.
If you intend to daily drive in the summer, I'd highly suggest a big radiator, possibly a dual pass? But managing your extra heat load will help reduce the stress on other stuff in the engine bay. Keeping things sufficiently cool will hopefully help things break less
