The Hemiguy was nice enough to deliver my set to the house and I was going to ask him why the long adjuster but we got off topic with Hockey. I have some shorter ones so will be changing them up. Will clean everything and will soak in oil never hurts when it comes to a bearing. I have not decide about the Stands, I believe he uses the same stands on the stock rockers style also. A friend also looks like he is going to buy a set and invite the owner of Hemiguys down so he can take a look at his T@D Spray bar set up on his 604 Barton Motor, hemiguy was very interested in seeing the Spray bar T&D system in person. Also the rockers are 1.6 both intake and exhaust.
