Pushrod Angle problems

Pretty vague question. Can be more specific? Maybe pictures would help. I know depending on parts combinations, people have had to enlarge pushrod holes in heads. Is that where you're goin with this?
Been trying to upload the pictures for a while, but the site isn't uploading them.
As far as the angle goes, I know the roller lifter are longer then standard, so how do you correct this?(I'll get a picture posted as soon as I can)
