vtec head?

hey everyone sorry for the noob question.
Iv got a d15 non vtec engine in my 92 si hatch with a blown head gasket.
now what im wondering is would a d16y8 vtec or d15b vtec head fit on my block?
since i gotta remove my head to fix the problem and my car is already wired for vtec should i go for the upgrade?
or should i just do a full vtec swap?
Thanks
