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

I dont know man. I think the market is too small. Plenty of people KNOW they are the best, but not many people have ALL the dough to buy ALL that it takes to make them work. First, there's the initial cost, then the 1200-1500 MORE for the right valve gear. That's a lotta coin.

I think Chrysler phased them out the same reason they phased out the Gen I Hemi. Valve train too complex and costly to make.

It would be nice to have them as a choice though. They would be billy badass on a hot street car. Somebody would have to have somethin REAL to pass you. LOL
