I need a little help here, I'm converting a 350 from flat tappet to factory roller cam. I'm using a roller 350 block with world products s/r torquer heads w/ guideplates, factory roller lifters, production lt1 roller cam, and manley 7.15 length pushrods. Everything seems just fine except for one pushrod that seems to get stuck, it gets bound up when pushed down between the hole and the guideplate.. its not serious and will pop back up with a light tap.. how do I go about correcting this? Edit: Upon further inspection it appears that the pushrod simply will not go perfectly straight into the lifter, it isn't very noticeable with the lifter on the base circle of the lobe but at higher lift it becomes a problem.. it only effects the one..

 

What rockers are you using?

 

Figured it out, didn't notice it at first but the guideplate was slightly crooked, straightened it out and all is well.
