Use a "soft spring" in place of your valve spring and it will work fine.

If the pushrod compresses the lifter, two things result. First, you lose some lift and as a result shift the pattern to the intake side. Second, you need to be at zero lash when you do this otherwise the results are skewed.

What he said.

On a setup where i'm not pulling the heads, I use a very soft spring. Of course if the heads are off, a solid lifter is used.
