It is certainly a good idea to be looking at other options besides the heads and blocks described in this topic. As mentioned at the very beginning, this topic was designed to gauge interest, there is no guarantee that any of these products will come to fruition, and the parts are probably still 9-12 months away, if everything goes according to plan. For my part, I'm pretty committed to making the heads and intakes a reality, but I don't have any direct control over the blocks. I'm sure things will get clearer as time goes by...
