The F11F had an afterburner but it was deficient in every respect to the F8U except for handling qualities, particularly on approach for landing. Which is why, after a brief operational career, it was relegated to the Blue Angels flight display team (about 40 of the 201 built were flown by the Blues at one time or another) and advanced flight training.
Although only 201 were built, there were two different production configurations, the short and long nose.
The short-nose airplanes also had the angle-of-attack sensor on the left side of the forward fuselage (although it was not on early test and production aircraft); the sensor was on the right side of the long-nose F11Fs.
That's pretty straight forward, although care has to be taken with respect to where the change begins in the forward fuselage:
Then there is the problem of sorting out what aspects of the various existing F11Fs on display are bogus. Worse case is the F11F that was formerly on the deck of the Intrepid Air-Sea-Space museum and is now on loan to the MAPS Air Museum at the Ankron-Canton Airport in Ohio. It is painted as Bureau Number 141783, a long-nose F11F, when it served with VF-33. However, it is actually a short-nose F11F, BuNo 138622, that spent its career at Grumman in flight test.
(It also doesn't have the wing fillets of the long-nose configuration.)
Even the best preserved example, BuNo 141828, shown here with Don Hinton at the National Museum of Naval Aviation, has a few (but minor) configuration issues.
Many of the F11Fs on display are in Blue Angels markings. However, most of these are not in the Blue Angel configuration:

There is a minor difference in the presence or absence of the antenna under the aft end of the canopy.
The NMNA F11F does not have the antenna, probably because it came to the museum from a VT squadron. However, here is a picture of a pair of fleet F11Fs, one with (211) and the other without (206) the antenna...
