Q: I’m going to drop a GM LT4 Hot Cam into my Gen I small block Chevy. What valve springs do you recommend for the best match?

The LT4  Hot Cam is a hydraulic roller with a .525-inch lift, and COMP’s beehive valve springs would be a great choice. Don’t forget—when upgrading valvetrain components, it’s important to always check spring fitment, installed height, coil bind, and retainer clearance.
