    Hey i have a set of comp cam 17004-16 roller rockers im just waiting for my push rods to come in to install and set up everything in my instructions it has me taking it to zero lash then half turn more for each valve. But further along it says for non adjustable rocker arms set to .020-.040 just wondering what i have adjustable or non adjustable. nothing im finding online is any help. Thanks! Gen 1 350. Bored .030 over camel hump 202s. With cam part number comp cam 12-238-2

    Your cam is flat tappet hydraulic and your lifters should also be so ... zero lash then 1/2 turn. I have the same cam in my 350.
