Hi can anyone tell me how I can confirm what I believe to be a standard 998 unleaded cylinder head?
It is casting cam4810 which I've seen referred to as a+ lead free cylinder head but I've also seen posts that say all a+ cylinder heads have this but are not all lead free.
It also has d 16e6 by the thermostat
A 4 by the valves for cilinder no1 and what looks like BIL by the valves for cylinder no4
