Mopar sb 273 rocker arm dual spring question

People have clearanced rockers for DECADES. That doesn't necessarily make it right. With low lift like yours, I think it's overkill for the B3 kit, unless you just want it DEAD RIGHT, which it will do. Are you going racing? You gonna do a lot of high RPM operating? If this is just a street cruiser, I'd clearance the rockers in a second and never look back. Is it right? No but it'll work.
