The Twin Spark Engines In Alfa Romeo have been in use for some years. these engines are difrfrent from each oter and it depends on what sise,, 1.6 or 2.0 or even V6 so without any information what engine you are talking about this question is not able to answear .
Never heard of twinspark v6. But certainly 1.6 1.8 & 2.0 Cant tell you about timing marks but if changing cambelts etc. would not attempt without using "CAM LOCKING TOOLS." It's the only assured way if you want to do it right. Good luck.
