Hmmm could be a collapsed lifter(s) maybe?

They can be a b tch occasionally. I'm assuming that all of the lifters were installed on the same cam lobes as they were in the first engine, and the engine has proper oil pressure and all of that good stuff ...
What method did you use to adjust the rocker arms and how far did you turn down the nut from "zero lash"?

I thought about that after I wrote it. I have roller rockers on my mind. Lol.
All of the pushrods are in the correct locations as well? You may have to either use shims or different length pushrods to solve this. Have you ever considered changing over to stud mounted roller rockers?

Jeez. I'm not doing so good on this thread.

I just reread your original post.

This is the same engine block that the cam and lifters were originally in, only it has been rebuilt. Correct? That being the case... Was the block decked and/or the heads milled? That will change the distance between the lifter and the rocker arm.
Other than the push rods, somehow, getting mixed up, I can't think of any other reason why your getting the valvetrain noise from the same set up.
Your probably going to have to get one of those adjustable pushrods to measure and see where you're at.

Also, make for damn sure that this is not an exhaust leak that you are hearing. They can be tricky devils...
This is why I like roller rockers. Especially on Fords...

Ok. That finally clears it up. Lol. Probably the dimensions have changed with the different block. Good luck and please update when you get a chance. These are the kind of problems that interest me the most...

Did you give them a good oil bath prior to putting them back in? And yeah, would've been better to have stored them in oil for those 8 months.
