Currently stock rockers. A close friend with similar 440 with a stick difference being rpm heads roller rockers with the XE275HL. I didn't ride in his car but we were talking about it and he expressed the same feelings. I definitely respect his opinion.His car did have a 3.91 gear.His engine was also professionally built. He pulled the engine out of his '71 300 which was an automatic and put it in a "69 B body.He felt the motor definitely worked better in front of the automatic. I was thinking the same way you are about the duration. After talking with him I started to wonder about that. Going to a solid cam makes sense.
