BC STG 2's are quoted at 264* duration, at 12.05mm of lift. this is why it's recommended you don't run these at high RPM without S/R, like you can with the S4's.

S4 are 266* and ~11.8mm lift
Compare the BC stg2 to JWT C1 and you can see that S&R are needed
JWT C1 is 264* 12.09, the BC stg 2 is 264* 12.05
BC stg3 272* 12.55, JWT C2 275* 12.7
