Can any one guess what he is making?
What I was watching him do last night was locating these brackets so the move on the same axis As the swivel bearing. He ordered the same lock handles for the top to lock them. Not to prevent up and down movement.
I told him that that the riser adjustment when using both fixtures will prevent up and down movement. He came back with this answer: "There is .001 clearance on the bearing races. It is critical to eliminate this movement to prevent chatter on the hardened seats. You would never see this with a naked eye so many shops don't care. I noticed this at the shop where I worked."
When he showed me everything he found on our new heads from "Shady dell" a while back. I couldn't disagree. And Ryan at Shady Dell never touched them they were right from the manufacture in the box. They look so nice all shiny and new the average person wouldn't see the defects. I didn't see them I bolted them on Years ago. The guides were not centered with the seats cause by something moving when being machined. Plus many other issues. The second set were prepped by the first Co. Bought on line.
The new heads we just bought from another manufacture had even more issues. Assembly line type manufacturing is never the same as a one on one machinist start to finish.
Don't destroy a motor. Whenever you buy a machined part have a local machine shop you trust check it. Its called "Blue printing" Checking "all specifications" at least twice .
