Default Sierra Cosworth '91 T16 4x4 - spark plug

I'm doing some works to my "young company life" with original 79 k km .... only one owner 8 me ) .
It's more then a year that i'm working on here .

So, I ask which are the correct sparks for my engine, Champion, NGK or Ford motorcraft ? Which number ?

I will map a little bit at the end of the restoration and adding some cv to about 270 - 280, with different exhaust, map sensor, and other modification .

Sorry for my english .
