Posting this in internal engine would gather a few more responses from you.
However ticks can come from other things, not necessarily a lifter. Where is the sound comming from (where can you hear it the most example: better from under the car, center of the car, etc.)

If you're using Mobil 5w 30 the oil turns thin as water when the oil gets hot. That'll make your lifters tick louder. I switched to 40 weight oil and the ticking almost disappeared. 
The remaining noise is from the high lift cam.
Use the suv/truck oil (I think it's 5 or 10 W40) and that will be a big improvment.
