No start no spark

The car was not starting when I got it. I found it had a bad head gasket and also the timing marks did not line up. I put the timing marks where they are supposed to be and cranked the motor. It was popping on two cylinders. Prior to positioning the marks when cranking the engine it did not pop and felt like no compression. After replacing the head gaskets and having the heads and valves checked to ensure no valves were bent I reassembled the engine. On cranking I have no spark. The timing marks are still aligned. I have power at the coils. I replaced the crank sensor but still no spark. What else should I be looking into? I do not think it has an igniter or does it?
