Prw stainless rockers

i have a set i tried to install and the throat of the rocker hits the edge of the spring not impressed with them one bit
We had some veeery slight interference between a few of the PQ aluminum rocker bodies and Edelbrock springs if we exactly centered the roller over the valve tips. We just shimmed the rockers off to the side a bit to correct this. The rollers don't need to be dead centered on the tips anyway. No real issues there in 1k miles.
