I wonder if i must use guide plates when using Non self aligning Roller rockers. I have read a lot of threads here but can't come to a conlcusion any way. The problem is that if a mount the guide plates there is some tention pushing the rockers side wise so they end up not centered on the valve spring. The words in green is swedish and says; Do I really need guide plates?

 

You don't need guide plates with those heads.

 

Great news!! Thank you very much for a quick reply.
