When dealing with the venerable SB Chevy, a good street performance engine can be built with mostly stock parts. Unless you're looking for a high winder, the stock stamped rockers are ok for engines that will peak around 6000 RPM with a hydraulic or mild solid cam.

Beyond that, you can get fancy.

If this is your first shot at a hi-perf build, KISS..keep it simple and safe.

With the SB a little can go a long way.
