hey man, I had the same problem, I am running Ferrea valves, the tips are shorter, from tip to keeper groove. The problem was solved with different retainers for my valve springs. So it brought my installed valve spring height lower , thus the rockers clear the retainers when valves are closed.

cheers sounds better than filing r/rocker. my plans have changed i am not using that mtr anymore but i will fix it anyhow do you have the part no of retainers.

Hey, you have to make sure the retainers you are going to buy sit snugly in your valve springs, you don't want them to be able to shuffle around in top of spring too much.
The set I got for my double springs are actually,,,,
Competition Cams. part no.743-16
these cleared my rockers but did shuffle a little in top of spring. not an ideal fit. But do work.
There are so many different size , so I have found. and spring sizes to.
Don't forget to check your installed hight seat pressure. A must for mild or street cam.
I have found this out,, the engine sounds chrisper and a lot more perky at start up and cold idle with high oil pressure, I running hydraulic cam. Just christ all round, I luv it!
