ive build a zvh a few years ago now im going zetec as that has a bigger scope for power over the zvh plus its less hassle, ok you have to either get an adapter plate or modify the head to take inlets & exhaust housings or get costom ones made up whereas on the zvh you have to block oil ports on the block & drill the side of it to adapt the water pump etc....both need the back engine mount modified but im not sure whether there is enough room for the 16v head
