this might be a dumb question. But are you SURE its not a blown header gasket? If the gaskets just ripped a little bit you probably wouldn't here it just idleing with the hood up. But when you get in your truck and take off its pushing the exhaust gasses harder causing that annoying ticking.

What is the cadence of the noise? Can you discern if it is coming from all cylinders or a single cylinder? Have you narrowed it down to Bank1 or Bank2? Is the sound intermittent or constant? The only time I've been able to hear injector pulses(over other mechanical sounds) is with a mechanical stethoscope.

I've heard .060 to .090, but I've heard tons of other opinions, so who knows which preload is correct. It's not a blown header gasket because I changed it when I swapped the lifter. Plus it ticks at idle. It really sounds like its coming from cylinder 7, which is where that pushrod with the extra wear came from...exhaust valve. But replacing the lifter did nothing. The sound is definitely consistent... Sounds too slow to be anything rotational like a flywheel, but seems just right for a pushrod to be flying off the lifter for a split second...
I am going to install the 7.425 rods when they get here, like viciousknid said.
