There is a little reduced friction by using roller TIP rockers. And even less friction if you move on to a full roller rocker. But that's not why most folks go that route. The REAL benefit is the increased accuracy of a nice set of rocker arms VS the oem stamped steel units. You can really take full advantage of the camshaft profile when ALL your rocker arms are at the correct ratio.

Agreed. If you're going to do it, go full roller to get maximum benefit.

For a basic daily driver, the stock, stamped rockers will work fine however, upgrading as mentioned above is well worth it. Stock, stamped steel rockers are not very accurate. You don't need to spend $$$ on high end roller rockers but I also wouldn't recommend going the inexpensive route and buying the cheapest roller rockers you can find.

When buying new rockers make sure they are for the proper stud size. 3/8" is most common for SBC. Do you need self aligning rockers or not? Since you will be buying rockers, might as well bump up the ratio at the same time from the stock 1.5 to 1.6. This will give you slightly more lift. 1.5 and 1.6 rockers are probably close to or are the same price.

comp cams high energy RRs are a nice budget option

You people and your exotic alloys, anti-friction stuff, and custom lengths are just complicating things. My rocker arms have lasted a lot longer than the majority of all those "special" types, and are made entirely of wood. Estimating the ratio is a little difficult, however.

And double check that if you do buy roller rockers they'll with the center bolt rocker covers and self align if needed.
