1975? 340 el tigre Parts info request

Hello all,
I just purchased a 1972 440 cheetah and in the box of "extra parts" I got the following

a box marked el tigre that has a solid state ignition in it from the NWIRE company part number 106D-06 181
also a cylinder head in a arctic cat box marked

artic cat # 3001-579 kawasaki # 11001-564 cylinder head (340)
it is setup for 2 spark plugs and stamped with 340/2A

also a cylinder with it stamped 340/2A

The holes line up with the head so I'm assuming they are for the same sled

Tracking down the arctic cat part number led me to a 1975 eltigre parts list.

Any info on this and what they are worth would be appreciated

Thanks
Brad
