I decided with the interest this head has generated, I would post a picture of the heads we began working on months back.
This head was the 12.6 degree, it's my understanding the raw castings are the same between both versions. Since I don't have an 11 degree version to compare, I have my opinions on the machining operations they are changing between the heads. It's our opinion for us to market this head, it will need to outperform the current heads on the market.
Flow data will be posted once we are nearing completion.
Thanks.
