They are not pressure fed. I run them with no issues on street engines. However I bush the lifter bores on every solid roller I build. If you don't - I'd get a full body deal that does have pressurized oil feed.
Gotcha. Looks like I'll be buying another set from Mike at MRL. Have around 3000 miles and maybe 15 passes on the set I'm running now and have no complaints whatsoever. Just was try to go cheap. Pretty stupid of me...
