I agree with you, but people have to agree with their pocket books for it to becomme a reality or I get hung out to dry.
If I go all out and make a really killer competition piece that is not the most streetable or that has higher associated costs, will people buy it. If I make a nice piece that barely trumps a ported head, will people justify the cost for a small percent better performance or will people after a short time, feel the need to come out with a edgy piece that outperforms mine? When it is all said and done, I will take as many road blocks to horsepower out as I can for a given price. What I am trying to weigh out right now is, if we go to a Duramax style injector that allows me to remove the connector tube, a roadblock to horsepower, will going with the duramax injector be putting a larger roadblock in its place?
The best thing about the 12v head is it's simplicity. With the help of people like Greg Young, we were able to come out with a great piece for a decent price and we did not have to re-invent the wheel to do it.
With the 4 valve head, there is much more room for change, improvement and ways to hang myself.
