Well, are you using stud mounted, or pedestal mount rockers? By you saying you torqued them down, I'm going to assume you're using the stock pedestal mount ones. There could be a bunch of things...those valves are closed, you need longer pushrods, your rockers could need shims, or it could be bad lifters. Please let us know what kind of heads/rockers you are using so we may be able to help out a little better.

Check the pedestal's to see if they are cracked. This is common if they were torqued too tight at some point.

Are they new lifters? If so they may be bled down. Are those pushrods bent? Is there any oil or debris in the holes of the ones that are loose? Pushrod cups may also be pushed up.
