Did you read my whole post?
I did my research 9 years ago, including talking Livernois.
I wanted the Raptor R heads and cams.
And I'm not about to go over a million posts.
I did read your whole post, and you said you didn't have a link.
First couple times i talked to livernois they said they were different...but the guys i talked to didn't know exactly what. But when i talked to the head tech he said heads are the same.
The only thing i have found is that the early raptors (10&11) had a "RFAL3E" code stamp after that, that code went away. Maybe the "R" heads are better?? Idk.
I'm thinking the RFAL3E head is like the old
DOVE head which is/was super desirable where as the D3VE is the same thing but doesn't fetch the price (maybe thats not a great example but you get the point)
However, today, if you order a bare head (no valves or cam) the part numbers are identical for the raptor and the super duty. Same goes for the valves, pistons, etc...
The complete head has a different part number due to it comes with a cam
