I don't understand what you are asking.

A top swap retains the formerly NA block and heads.

You can't topswap and call it good. You have to tune for it. Having the higher compression and Boost causes more heat, which causes detonation. Flow mods, cooler plugs, and cooler air (intercooler) and tuning, are all ways to fight the detonation, AKA knock.
