Average Safe Boost level for a LA eng
If you are using closed chamber heads, simply radiusing the sharp edges of the deck could dramatically improve the engine's tolerance to boost. Part of it comes from the reduction in compression ratio from the material removed, and part comes from the improved combustion characteristics of the radius.
Although a Chrysler 2.2 Turbo head, the principle is the same.
