Visually, there is no comparison...and everyone knows it.
Performance wise, if you build a HEMI like a wedge, it will run like a wedge. The opposed valve layout is a COMPLETELY different animal and must be built to reflect those differences.....especially in the intake/cam/headers department.
If you have nothing to start with and decide on a conventional HEMI deal, don't waste your time with any cylinder head other than a Stage V and if N/A power is the goal, step right up to the Millennium version.
Doing it correctly the 1st time will save money and aggravation over the long haul. There are a lot of good shops out there that build excellent engines, but there are very few who specialize in getting the most out of HEMI engines. Dealing with the people who are most familiar with a particular combination is simple common sense.
If saving the last dollar is important and what you have to look at every time you pop the hood isn't, there are plenty of good wedge combinations to consider.
