1962 Mopars, 361/305 HP

More detail:
I just thought maybe the 1962 361/305 had the hottest setup (ie maybe solid cam option) because it seems like all the Nationals winning 361/305 cars were 1962 cars. NHRA says the 1961 361/305 offered a hyd and solid cam, so I figured maybe 1962 did as well. From the LIFT, it looks that way but those NHRA Blueprint files are vague sometimes.

For the FACTORY stock cam I've seen ranges of 252-252 duration, .390 .390 lift to 268-268 duration, .430 .430 lift.
That's for 1958-62.

NHRA Blueprint files show the 1962 lift as .444 .456.
305 361 DP .020 Flat 2080/1660 444/456 .020 Outer w Damp

From other engines in the NHRA files I would *GUESS* that's a solid cam.
For example below is the 1961 NHRA Blueprint.
Look how many times the same HP engine offers 2 or more cams.
Anybody know which cams there are (I'm guessing .430 .430 is hyd, .446 .458 is solid?)
And which one Kempton ran for all those wins (guessing the bigger solid one?)
Anything on duration or even part # etc appreciated.
