The way I see it, it don't matter if we technically need another 500 hp head. The fact these companies are willing to invest into the LA platform means they feel there's some future worth investing in, more mid level competition means possibly more people building 450-550 hp engines and some of those will want to build higher meaning at some point the 550-650 hp parts might grow in demand and possibly higher which might at some point make companies invest in parts you want. But if there little demand and investment in the 450-550 hp range unlike higher output market will grow.
