Are there any important reliability mods that the LQ4 needs while I'm in there?
The engine is out.......this is the time to do this stuff.

I'm in the same stage as you are and bear in mind, my build is starting to spiral rapidly to a completely different level than what I was starting with....
Keeping my bottom end (short block) stock and left alone (for the moment). Changing the oil pump and timing chain. Replacing all seals and gaskets throughout engine. Will get the double bolt clamp on the oil pickup tube.
I have a set of 243 heads that are freshened up but are probably now getting cnc ported and polished with oversize valves. I just got my tick cam kit with a 227/235 .618/.605 cam and BTR springs, valve retainers etc (will probably upgrade some of that to titanium before the heads are assembled). Replacing the lifters with a set of morel lifters and a set of new trays. New pushrods of course...
I'm going to upgrade the rocker arm trunnions with the Straub kit.
I bought an '11 LC9 intake for the bigger runners, bigger tb and bigger dual fuel injectors.
That should cover most of the standard upgrades (at least up top). I think there were a few more things on the list but can't recall offhand.
It'll be ready for a 408 kit later and should be plenty of fun for now.
