So what will help against knock since I read on another thread of Halons that Shane was saying 2jz motors knock alot more then others. Will aftermarket valves with different shaping to them, cleaning and polishing of the combustion areas on the head and a full coated piston running 9.5:1 compression on e85 help prevent the knock that an otherwise more stock 2jz motor would produce?
