It is non-interference, no worries there. Sounds like a valve timing problem. Most common thing is to use the wrong mark on the cam sprocket. The locating pin that connects the sprocket to the cam must point straight down toward the crankshaft. Next common problem is that the crankshaft sprocket comes loose and shears the key off, so even though all the timing marks are right, the crank is not where the crank sprocket says it is. Take out one or four sparkplug (they both move together) and put a straw down the hole. Turn the engine until the straw is at it's absolute highest point. Then look at the crankshaft sprocket to ensure that the timing mark points directly at the mark on the oil pump case. It should be pointing straight up at the cam (not straight up at the heavens, as the engine doesn't sit straight in the car. This ensures that the crank sprocket is properly indexed to the crank. Then, align the "E" mark on the cam sprocket with the mark, ensuring that the pin points down at the crank.
