You need full fuel system not just injectors.

Colder plugs as Josh mentioned. NGK 7 or Brisk 14

Proper crank case ventilation.

Octane. Pump gas alone isn't enough unless you plan on running low bost(6-7psi). You are adding boost to a high compression engine with very tight ring gaps and marginal strength pistons. Ethanol works well here but many areas do not have it. Other options would be alky injection or install a cam to bleed off some dynamic compression.
