Rocker arms for 408 build

12many said

For a street cruiser with a 5800 rpm target and lift of .525” max, doing stud relocation and/or using other specialized components, or any combination of fixes, is this common, recommended, something you or others well versed in these things advise and do as a matter of course? Seems to be way overkill in this case. Sure, if one wants to do that by all means, but using factory or the MP rocker setup? One would think at this level just using quality components, correct length pushrods and good assembly is all that is required?

If stock rockers and stock length valves are used, it should be fine. But, if it's good enough for a roller rocker, it's good enough to have good geometry. That roller tip changes the geometry so drastically, I won't let anything leave the shop without being corrected. I will recommend a stock rocker on a mild build every time, if the customer isn't willing to make the necessary corrections for a roller rocker. So, yes, it is common, and a matter of course in my shop. I've seen too many broken parts to want that liability on anything I build.
