The bottom line is, I am sure a Gen 1 truck long block and a Gen 1 Standard Long Block and a Gen 1 Boss Long Block will all run with Standard Software with a Standard Manifold even thought the cams on the three engines are different.
Very Interesting!!FYI, late build 2012's had boss heads installed. Hell some builds ended up with one boss head and one gt head.
No. Truck motor has a different firing order due to different cams. This cannot be adjusted in the tune. You must repin the engine harness (coils & injectors) to run a truck engine with mustang software.The bottom line is, I am sure a Gen 1 truck long block and a Gen 1 Standard Long Block and a Gen 1 Boss Long Block will all run with Standard Software with a Standard Manifold even thought the cams on the three engines are different.

Its been talked about on this very forum with pictures i might add. This is why some heads have to be clearanced for cams and some dont. My heads didnt need clearancing for cams. My car is a late 2012 build, one of the last to come off the assembly line.Weren't the BOSS heads CNC ported from the factory? That's the whole reason Ford changed the casting in 2015 to be an "as cast" BOSS style head. I find it hard to believe that the notably more expensive BOSS heads just got plopped on regular 5.0 engines for plain ol' GT's.
What's your source for this information? I'd like to read more about it.

What would you suggest Ford do with these heads after the Boss Program was cancelled? Crush them for beer cans? It's my understanding 20000 heads were CNC's for 10000 Boss Engines of which maybe 8300 were used in 2012 and 2013.Somehow I TOTALLY missed those posts. Interesting.

Cnc'd for boss cams. Since the ports are the same it makes no difference to use them on GTs with the smaller lift GT cams.What would you suggest Ford do with these heads after the Boss Program was cancelled?

You can't purchase a Boss Long Block unless you turn one in. They kind of have the same rule with the Clusters.FRPP was selling them for a few years. And OEM's are required to have service parts available for 7 years after production ends.
Are you sure? This is the first time I ever heard of that.The intake and exhaust ports were CNC'd too.

I was aware of higher lift cams (+1 mm), intake, and higher rev limit to take advantage of the shorter runner intake.
Interesting. Guess I need a set of Gen2 heads! (when something needs work on mine)"When a casting emerged from the Windsor foundry, CNC machines went to work to massage the unique BOSS casting which, to the naked eye, isn’t much different from the standard Coyote head. In terms of power and function, how-ever, it is surely a different head. With the BOSS head you not only get improved function but also strength in a better-alloy cocktail. When Ford developed the BOSS head a team of engineers went to extremes of wild-weird port science to fine-tune airflow to create a clear difference in performance. Ford engineers worked day and night on intake and exhaust port shape with grueling dyno tests to determine how much they had gained. It didn’t happen all at once. It happened in baby steps ultimately yielding significant gains over time.
As engineers massaged intake ports they found that conventional port logic didn’t always net them improvement. Improvement came with minute changes in port shape. Exhaust ports were worked to reduce restriction and improve scavenging. Ford engineers achieved improved flow by also lowering the port floor."

Further the casting was changed to deliver these improvements in "as cast" form in 2015. This was widely reported as fact in 2015 at the debut of the new Gen2 engine. Also when the better BOSS spec rods became standard across the board in car and truck engines.
I just installed the Boss oil cooler on mine.The 2015 cams were more or less the BOSS cams as well.
"Ford’s Coyote V-8 carries over as well, although it receives more substantial changes. Mustang engineers used the low-volume Boss 302’s V-8, a glorious-sounding 444-hp powerhouse, as its performance bogey. Unfortunately, the Boss engine incorporated some expensive manufacturing tricks that Ford couldn’t possibly use in a mass-produced engine, like hollow intake valves, sodium-filled exhaust valves, and CNC-ported heads, so it had to look elsewhere to approach Boss power levels.
While the new engine doesn’t quite come up with triple-fours, it does pump out 435 horsepower at 6500 rpm and 400 lb-ft at 4250 rpm, increases over the old 5.0 of 15 horsepower and 10 lb-ft. The extra output was achieved via improved head flow (which Ford was able to accomplish through casting rather than expensive machining), larger valves with increased (Boss 302–spec) lift, stiffer valve springs, the Boss’s forged connecting rods, and some aesthetically pleasing tubular headers. The compression ratio remains 11.0:1, and an oil cooler is now standard."

I take the HP ratings with a grain of salt. As my stock gen 1 w/412 crank HP puts over 400 to the wheels with just a tune, and CAI. But this got me thinking of going to Boss cams and intake or boss cams and 18+ intake. Hmmmmm
