LA aluminium heads on 5.9 magnum

Hi guys,

can somebody confirm please that i can run LA aluminium heads (edelbrock knock off) on a 5.9 magnum block if i use the PRW 3231812 rockers?
Obviously along with hollow pushrods, but i will have to measure the length first.
Some people say you need to drill the adjusters of the rockers, some people say you dont.

Thanks for the help!
