This is a Sapphire cosworth

I need the torque settings for the studs that hold the camshafts in please ? (Think they are the rockers they hold in place!)

Basicly the studs rounded out of the head so have it heli coiled but need to know what the settings are to put new studs in and the nuts please ?

If anyone has a pic of the haynes manual that owuld be great ?

Also whats the rocker cover settings does anyone know pelase to ?

Thank you!
