i currently have a b18b1 engine in my teg. if i understand correctly a itr head will fit on my block to make it an ls-vtec? if i need anything to do this plz lmk. thanks.

 

any b series head will, but you need more than just the head.

decent set of studs while you're there
oil feed lines (might as well get ls/vtec conversion kit)
chipped vtec ecu

just a few, can't think of anything else off the top of my head.

Its a lot harder to do that just bolt up....but you def won't be dissapointed with the outcome if you do it right.
