Is the improvements to the new LA heads, enough to not reproduce the W-2 head anymore

W-2s are good heads but I'll take aluminum for many reasons. I have a good set of ported Edelbrock's and a set of Indy's that are going on my 434. If you really want to make some steam with a small block you need a set of W-8s or W-9s.

IMO we as Mopar guys shoot our self's in the foot when it comes to new stuff. We don't embrace new improved technology and design like other brand loyalist do. If you don't believe me look at the popularity and available parts for GM's LS engines. How many times have we heard "I won't buy it because doesn't look like my (whatever) head does".

I will lay part of it on Chrysler, to a large degree they don't support performance or race enthusiasts. If you want a travel cup, floor mats or a sweater they can fix you up. Walk into any dealer and try to order a performance cam or a better set of heads for your 5.7 and the parts guy will look at you like you have three eyes.
