You can run full roller rockers of the correct rocker ratio for your combo. No "Over the top" style such as Jessel. or shaft rockers on a chev or individual stud rockers on something like a 340/360 MoPar. You have to maintain the OEM configuration and mounting. This came about to increase reliabiliy in some engines because of the extream valve spring pressures being used on todays stockers.
