I got the morel drop ins for 200 from ws6 store. In the install instructions, it talks about adjusting the lifters upon install. I thought that all u do for these is do whatever pre oiling they suggest, drop them in, and measure for rod length.

You just have to measure pushrod length for proper preload and that is it. Once there in no adjustment. Of course oil them when you install them. They like less preload then LS7 lifters. For my iron 5.3 with aluminum heads Morel told me .045 for preload. Aluminum block with aluminum heads most go with .050 to .060. Of course pushrods come in .025 differences so you just need to get close to the preload for your setup.
