I also found in my notes a rather poor reproduction of a poor reproduction of two detailed maps of the Pleasant Hill battlefield that were compiled by illegible author names (that's how hard it is to read the copies.)

However, from this map I can make out the following artillery on the field if I squint and guess...
Moseley's Battery (7th TX): Two 3" rifles, two 6 pdr guns
Val Verde Battery: two 3" rifles, two 6 pdr guns
West's Battery: two 2.9" parrott rifles, two 12 pdr howitzers
Haldeman's? (mostly illegible, in front of Waul) Battery: two 12 pdr howitzers, two 12 pdr "smoothbores" (most likely Napoleons)
Etter's Battery (Arkansas): No gun types listed, 4 total
??? Battery behind Parson's brigade, lists 2nd Lt. Jim Wright, 4 guns total, two read as howitzers, two above that are nearly illegible, but look like "Guns"--and the word before that *might* fit "rifled"...conflicting, but "smoothbore" is used in place of "gun" for 6 pdrs elsewhere, so flip a coin on filling in the blanks.

On the 2nd map of the farthest advance a "Conners?" Battery (13th TX) of four guns is also shown on Scurry's right flank.

Again, it would take some cross checking with the O.R. and such to pin down what the question mark units are.
