You pull out a drawer full of tools and it slides out nice and easy with very little effort at all. Now take a new snap-on tool box (roller rockers). Thats because its metal sliding on metal. You pull out a drawer full of tools and its kinda hard and takes some effort. Take an old tool box for example(stock rockers). Roller rockers are in my eyes def worth it. I think that is mainly for flat tappet lifter and not so much with rollers. Some say that lifters create a wear pattern on the cam and if you change them then there is a possibility of the lifter getting bound up and smashed. Aftermarket lifters and our stock lifter look identical. Oil gets built up in the plastic retainer sleeve and can rob you of hp. If you do that then I would drill 1/2 inch holes in the plastic retainer sleeves that hold the lifters so that oil can escape. Beleive it or not I found those cheapest at the dealership. However, you do have to pull the heads which means you need new head gaskets and head bolts. Spending $300 on lifters is a hell of a lot better then spending $3000 on a rebuild if something goes wrong. I'm just one of those people.do it once, do it right. I don't have excessive wear nor a lot of miles. You only need that if you have flat tappet lifters and are switching to roller lifters. You do not need a anti-rotation link because LS motors already have roller lifters. If your truck has a lot of miles (80K +) then I would change them. If you pull your cam out and it has a big wear pattern then I would change them. Stock LS lifters are good up to about 400-500hp. What about rocker arms, is there any gain with them? Not are they worth the price but just is there any gain? Comp cams, harland sharp, Yella Terra is there one better then the other or does one not work on our motor? when you start to deck heads and use thin head gaskets do you need adjustable, or do the non adjustable work as long as the push rod is the right length? 600 lift should i run comp cams, gmpp, or morel lifters? Do all the LS1 lifters work in our motors? If i buy a set do i have to buy them with the antirotation link(not sure what it's called), the bar that connects 2 of them? I know most say aftermarket lifters aren't worth the price, but when can you justify them? Do aftermarket lifters handle high lift cams better? Do stock lifters float down or crush with a higher lift cam and harder spring rates? If my cam is over. What a differance that they make, it pickes up rpm's faster and a noticable horsepower gain, aprox. The rockers look like they were going to hit the side of the heads but there just enough of a cut away in heads for clearence. I wish that I would of known this before I started this mod., there were no instructions or warnings with parts. I had the valve covers off 3 times before I had all the interfering lugs ground down enough. These were interfering with the valves from closing all the way.

angle on the high spots of the pertruding lugs (from the reverse sided threaded lugs, on both covers) and pening down the windage shield front locator on the drivers side valve cover. I had to modify the valve covers by grinding a 45 deg.

The hard part is that they are not just bolt in and go. I just put on a set of Harland Sharp Aluminum Roller Rockers 1.7 ratio with dowel pin between two rockers, this last week end and I love the performance gains that I got from idle to wide open throttle. What about rocker arms, is there any gain with them? Not are they worth the price but just is there any gain? Comp cams, harland sharp, Thanks for the help!
