Solid roller Question
In an effort to increase reliability and longevity, I am replacing my conventional solid rollers with "Endure-X" style, being this is mostly street-driven. Should I use oil-feed restrictors in this application? TIA

No, because the reason roller lifters fail pre-maturely in a street engine is because the rollers overheat, and the additional oiling helps to cool them. You don't want to add oiling by switching to lifter bodies with the oil groove in them, and then turn around and put restrictors in place farther back in the pipeline - you'd be defeating the purpose.
BTW, I ran the early version of the Endure-X lifter for 22k miles with no problem.

I agree with lifter with priority oiling to the rollers I wouldn't use the restrictors, I use restrictors with the older style CC 818's that had no oiling to the rollers, 25,000 street miles so far, I just replaced one lifter about 500 clicks ago for brinneling of the bearings in the roller, the others are still going strong 
Always remember not to let it idle too long when running a solid roller on the street, give it few shots of gas every few seconds, always gets the guy beside you going too at a light

I got ~40,000 miles out of the old stye Endur-X lifters before one started to fail. I replaced all the lifters with the newer re-buildable style Endur-X. I have not run oil-feed restrictors. It seems like that would defeet the pressurized oiling of the rollers with the Endur-X lifters.

As a solid lifter engine it should be capable of 7K++ or it`s not worth it`s salt. Therefore the valve springs are very critical as the roller must follow the cam profile and not be bouncing at high rpm. In conjunction with the valve springs a rev kit is also a wise choice to help prevent the same issue. Unfortunately the lifters are heavy so they must be held to the cam and the rev kit does just that.
