I'm trying to put in the new timing belt but I don't see the timing marks on the engin block. Do I just need to line up the marks on the pulleys with the marks on the new belts? And if I need to pull out the heads for service how can I do it without pulling the engine?

My timing belt wen out on my rs while I was starting it. Any idea weather this engine is an interfierence or a free wheel style engine? If it is interfearence style is ther a way to pull off the heads so I can rebuild them without pulling out the motor?
