Re: High compression engine and pinging
11.2-1 with iron heads is gonna to beat the pistons apart from all the pinging. DO NOT just go out and drive it even though its pinging. You will be sweeping the engine up when the internals exit via the window they make in the oil pan. Your best bet is to find something else to drive daily. You need over 100 octane to safely run that engine if it does indeed have 11.2-1 comp.Tickers suggestion will work also but if you pull those heads off to change gaskets you might as well just swap them for something with a more reason combustion chamber size.
