It probably has an angled head design, almost definetely not a Hemi however. Hemis have many undesirable characteristics for street vehicles, like carbon build up, inability to meet emission standards etc. You'll notice that even the Chrysler 5.7-6.1 Hemi, really isnt even a Hemi. Its what we call a Semi Hemi. The combustion chamber has a very noticeable flat spot in it to help with the above mentioned issues. The new Hemi is a fantastic engine though, definetely on par with GM's LS smallblocks in design.
Those emissions issues can be resolved with Direct Injection, VVT, and other modern technology.
The 5.7-6.1L are above par in comparison to the LS series. They require a lower compression ratio to produce more power. The LS7 7.0L has a compression ratio of around 11.0-11.1 to 1 compression; meanwhile, the 6.4L HEMI produces similar to slightly more hp and more torque while only having a 10.5 to 1 compression ratio and also is significantly smaller. The 6.1L produces 425hp & 420 ft-lbs of torque with a compression ratio of 10.3 to 1; meanwhile, the LS2 6.0L has a compression ratio of somewhere close to 10.9 to 1 compression and only produces 400hp & 400 ft-lbs of torque. Although the 6.1L is larger the difference in cubics is 364 (6.0L) and 370 (6.1L) only leaving 6 cubics which is really insignificant.
