what the vtec conversion kit does for you is reroute the oil in the head (i believe) so that he does not have to tap the head for a new oil line... it saves you the :noes: of drilling into your head... he still has to...

1)remove old head
2)replace all bolts with OEM or ARP
3)replace intake/exhaust manifolds
4)if knock sensor is an issue it needs to be bypassed or added
5)most likely resurface the head to be on the safe side
6)plug the old oil feed line

umm that is an incredibly rough idea... but there it is... check this out for a full detailed write up
