273 rockers on e-heads

years ago, ran a 1.5 dia springs on my 340, had to clearance 273 rockers to clear them. i found a comp spring , was 1.44 dia, had no clearance problems, 926 is spring number, has a high rate and enough pressure . just food for thought, put beehive springs on it. btw, ran engine to 7500 in traps
