I'm building a mild 401 street engine for my Gremlin, and I two heads to choose from. the first set is casting number 3216090 - from a 360/401 with 58cc chamber & stud rockets. The second is casting number 3231475 - from a 360/401 with 58cc chamber & bridged rockets. Which would be the better set of heads? I do plan on running a set of Roller Rocker Arms. Or should I just buy a set of Edelbrock Aluminum Heads.
