If you want it to be as reliable as possible, you may also want to add VTEC oil squirters and a properly doweled-in OEM block girdle. The main reason you hear of LS/VTEC and B20/VTEC failures is because they lack the proper oiling components, or installed a block guard improperly. Bad things happen when you try to just slap a VTEC head on a non-VTEC block and expect it to be able to work as well as an engine designed fromt eh ground up with VTEC and high revving in mind. For a while, a lot of people doing LS/VTECs would go out and get a Z10 block girdle, and just bolt it on, expecting it to help. Even the Z10 girdles need to be doweled in, or else they can tweak the bottom end out of allignment. This is the prcoess to properly install an OEM girdle:
