This is a great thread. For clarity sake I have taken all the attachments and put them into the Photo Library and then linked them here in order.
Not sure what is going on with the last photo (which leads to Twisted's question) . . . but the previous images show the head on the block.
For me the troubling thing is what to do about those push rod angles . . . With roller lifters the push don't need to spin but with heavy spring pressures how does one keep them from flexing?
Moreover, the push rods are leaning out of the plane of rocker motion. This will cause a sideways thrust (instead of just straight up) - effecting rocker ratio and potential stress/wear.
