Absolutely!!
I have done numerous RB timing belts and a few others. The Gates belts have lines on the. If you point the dowels on the cams up and set the bottom end to TDC then line up the belt marks with the punch marks.
Of course its VERY important not to turn the bottom end independent of the cams, otherwise the valves will hit the piston tops and bend, if that hasnt already happened. The way around this, remove the cams so the valves arent depressed, easy.
