Any B-Series valvetrain is compatible right?

I just wanna make sure that the ITR Valvetrain would work on a GSR or B16 head? Also will any B-Series valvetrain work with any other b series head? eg. B17 head with ITR valvetrain or B18a head with c1 Valvetrain??

Compatible Valvetrains and will yield the same open and seat pressure no matter which head are:
B18C1, B18C5, B16A, B17A

B20 and B18A/B valve springs and retainers are totally different and are not interchangeable in the VTEC heads.
