Lifters are new... The shafts are on correctly...The ticking isn't horrible but there is some valve train noise. it doesn't sound like the motor is coming apart or anything. Maybe I am too OCD about noises in the motor. I have never used aluminum heads before. I'm just a bit paranoid that something is going to go wrong. I can tell you the 318 it replaced never ticked. I had planned on going out and working on it tonight but I got home late and can't. Probably be Friday night before I can dig deeper into it.
