It was a 16v head on a std mondeo bottom end
Ive got a ported & polished head as well
May change things at a later date, I wanna get the thing on the road asap at the moment.
It turned out the head wasnt on the block and only the bottom end was supplied.

Its just cost dude
Its gonna cost me silly money as it is, and I think the power it makes will be neigh on unusable anyway
Answer me this then, WHY do people do ZVH, when it would be MUCH easier to leave the head on?

The problem with the ZETEC is that it was originaly designed under the Zeta name as a 1.4 to 1.8 lean burn carb engine and it was only after the EU making cats compulsary that it was quickly adapted for 1.6 to 2 ltr EFI use. The head was therefore never design for big power leaving little room for us all to modify it. If you want big power the answer is not to use the Zetec, but if you want reliable and economical power up to 175 bhp it is the engine of choice. Lets face it 175 bhp is enough power for most of us and the fact that it pulls from 2000 rpm makes it feel a lot more powerful.

It's been PROVEN that the zetec head flows a shitload more than the CVH head
People make ZVHs because they're stupid... Take the shit bit of a zetec, the bottom end. Then spend LOADS of money making it low comp like the CVH already is. Then you take the shit bit of the CVH, the head, and spend loads of money making it flow almost as much as the standard zetec.....
WHY DO THAT!! It only really makes sense in NA form. in something like an XR2 when you've already got carbs and what not on the CVH and you just want a bit of extra capacity. Then adding a 2.0 bottom end is a cheap useful idea.
Trust me, the 16v head will flow more air than a well modded 8v one.

i would say go with a zetec head its gonna cost about Ł200 for both addapter plates to use the cvh inlet and exhust manifold but sure standerd head and cams are good for 330+ bhp ( not sure were from tho lol ) + it will save time with blocking the oil ways ect i seen full heads sell for Ł50 and u can def mack alot of money back from sellin your head all of that IMO of corse lol

Right. When biult, your ZVH will make what, 280bhp?
If you go full zetec with your existing manifold etc, what do you think it will make? More? Or less? As your head needs Ł250 spending on it why not go for the zetec?
AAAAAARRRRRRRRRRRGGGGGGGGGGHHHHHHHHHHHHHHHHHH

You've also got everything you need for a zetec......

agreed ZVH will get you just about all the power you need in a FWD escort, but a full zetec will just give you that scope if you want it at a later date.
and fyi the stg2 box won't handle that power! You need a stg2+ i would get that done BEFORE it craps itself!
My stg2 went with 250bhp, and loads of other people have had them fail as well with less than 300bhp

You can't deny that the zetec head flows more than the cvh........... No matter what your engine is producing, or what jamsport have done with whatever, it's still a fact.
