With a 180F stat, I would guess you are just about 100% open at 194. With all the work you have done I would have expected a little cooler, although this may be an improvement from your previous temps.
With all the work done, wonder if some trash floating around has found the path to the top of the stat and has some of those small metering holes clogged up? That can shift operating temp higher (as less hot coolant enters the chamber to mix it up with the cooler coolant coming from the lower hose).
BTW, good work and pix.

Very odd!!!!!! The new rad I put in had the plug for the sensor. but the old rad I pulled out had no plug in that location. (or in any location for that matter). just a spot where they would drill and tap a hole. sooooo where might my temp sensor be located....in the block? ( no SAI) now that I have a new rad my aux fan seem to come on at low temps. since the new rad and t-stat ( fan clutch will go on when ever i can get the old one off) I run 188-195, 200 when climbing steep long hills.

So, I just finished changing out my radiator. First time, only took me 4-5 hours (one of which was spent walking to a store to buy last minute stuff -I'll explain why...). OK. So, most importantly, I went with a Silla 7868A from Amazon.
1. $160.00 delivered to my door. Amazon said 3-5 days shipping time, I got mine 2 days after submitting order.
2. LIFETIME WARRANTY
3. Branch location located 20 mins. away should I have to return for warranty, I called and so far they do keep these in stock at their warehouse, cost: $280.00... So stick with amazon purchase and service through branch office.
4. Self explanatory swap. Just make sure you either buy a new temperature sensor or do what I did, get a wrench, pull it out. CLEAN the brass tip with a rag until shiny, wipe any debris off threads. HERES WHERE I HAD TO WALK TO A STORE: Apply Teflon tape to THREAD AREA ONLY (don't want any teflon shards breaking off inside radiator) apply new rubber o-ring (included with radiator purchase on screw that you removed to replace with sensor) on the temp. sensor. Screw sensor on.
5. I took a shop vac and slightly covered an inlet tube with palm of hand, shop vac hose to other inlet tube. Found that it DID have a few aluminum particles (about the size of sand, very few) from manufacturing process. YOUR WATER PUMP WILL THANK YOU.
6. You do not need to take front grill, etc off your truck. Simply remove battery, followed by 6 #13 bolts holding battery box; unclip MAF, move MAF out of the way, remove air filter box.
All in all, I replaced: Radiator, Coolant (obviously), Coolant reservoir tank, Coolant reservoir tank cap. Total cost:~$240 Savings: ~4hrs paid labor, parts (depending where you get them, I'd hate to know how much the dealer would want)
