Boost with 12:1 & pump gas possible?

You could probably run it if you were to decompress it as much as possible with a headgasket. You would have to run race fuel or alcohol, the coldest plug, water meth with any boost, and of course an intercooler, not to mention low boost levels and have a very nice waste gate that won't fail. You would likely be better off taking the heads and slapping them on a stock 360.
