ls/vtec ??

what do i need to make an obd1 b16 head work with my obd2 ls block?

OBD doesn't play a part in matching a head to a block, only the head to the wiring harness in the car.

You will need to tap and run an oil line for the head, and drill in a couple dowels to make it sit right on the block.

Oh wait there's more, here is how to with pics, how nice....
