Alright my friend keeps telling me that you can swap the H23 head with a v-tec. Sevral people have told me it cant be done and that the H23's bottom end wont hold it. Who on here has done it or knows for sure

 

yes

 

So is it a direct swap? What is needed to convert / would it even be worth the time and money vs buying a H22
