Please school me on this motor

LOL, yea, the lil'things. I'm dyin to get a new HEMI and see up close what's going on. Pictures in mags don't allways cut it the way I like it to be cut up for me. I wanna see and touch up close and in person. There a lil'weird looking considering for the past 20+ years of me getting into and tearing down engines, it's been a few sbc and lots of sb chryslers. You kind of get used to seeing a certain something after awhile. And then suddenly, theres this china wall that looks like the great pyramid in front of you, heads that practicaly meet and an intake with a "V" at the bottom. WTF!?!?!?! Ha ha ha ha
