Help with Honda vc

Ok, Im using HK HP activation and back HK -> cr.RH->FP headbutts for anti air. Now the dummy either airblocks the headbutt or if I wait the dummy stand blocks the headbutt or honda just stops and misses it alltogether, What am I doing wrong?
I can do the combo if I turn off auto guard but that would not be realistic soo…

any ideas? or other vc’s as well?

make sure the roundhouse hits twice. if it does and the opponent is not knocked down, you may have to set a dip switch. (row 2, star 10).

Thanks , Yeah I think i wasn’t doing the standing HK deep enough.

Another anti-air one i use is (VC3)Deep B+Roundhouse, Roundhouse Flying But Drop, then do FP headbuts
