You're not going to get noticeable power increase from just the less drag IMO.
However, it will stop side loading the guides, so they will last longer. It will stop breaking the tips of the valves like the stockers do, and they will oil the top end better.
As for power increase, its going to allow for more lift. My turbo cam is as big as you can get on a regrind, so I'm going to go from the stock 1.5 ratio up to a 1.6 ratio.

well with the low rpms of the diesel, and stock cam id never worry about the stock 7.3l rockers.we have no issues to speak of of course.
however i went with higher ratio rockers when i swapped cams for a gas engine back in the day.i know there's a benefit there.
those running stock cams,could probably find better uses for the $,wouldn't you say too or?

For someone rebuilding an IDI and wanting it to "last forever" the roller rockers could be a cheap investment.
For someone with an IDI wanting to get more "performance", yes there is better things to spend that $450 on than roller rockers.

Sounds good to me! If I run typ4's torque cam, would I want to keep the stock 1.5 ratio or something else? Let me know if we get a pool going for that group rate (if they fit...) I'm interested.
