Well it's kind of Zetec related. :P :lol:


Which CVH head is the one to use for a ZVH conversion?

Is it the early hemi one or the later lean burn one?

Or does it not matter?

Cheers. :)

i would assume the hemi head would be used as thts whats on the rst's
although i think you need to machine the lean burn head if you want to use tht.

could be wrong tho, fairly sure tho

Hemi head is the best for the job!

I believe you can use the lean burn head......but hemi is the BETTER designed and better flowing head for the job.

I've got a 2.0 zetec block all zvh ready if you want! :P

Hemi, but don't do a ZVH.

You have to block off oil routes, so all the oil flows into the head and can't return fast enough, so starts pishing out of the rocker cover breathers.

For less hassle, you can have a full zetec.

He's right, why ditch the much more efficient Zetec head?

No no, sorry.

This post has to go in the ZVH forum.
:lol:

But yeah, my research found that both worked, but the Hemi head was better than the Lean.

dont bother, why go through all the hassle of converting the block just so you can have less power, less torque, sh!t fuel econemy and cold starting from a shonky old carb, when you could just drop the zetec in, wire in 7 wires and have a better engine?!

At the end of the day I don't want a full Zetec engine, it's that simple, I want to maintain the original look of the engine bay. I thought using a Zetec block with CVH head would be the easiest way to create a 2L CVH.

However people seem to be saying that a ZVH is a big load of bollocks and complete waste of time, so I might as well just forget it and stick with the 1.6 CVH as that's clearly faster.

2litre ZVH with a TT kit would preserve originality and give performance.

I was thinking more along the lines of 2L ZVH with twin carbs, but yes... providing I can find a TT kit for the DFT and the DFT can be jetted high enough for a 2L engine. :lol:

ollie you w*nker :blub: not saying a 2.0 zvh is a load of bollocks, it just makes more sense from a work/money/power/econemy/reliablity view point to run full zetec. it all just seems like alot more hassle for lesser gains.

Stick with the CVH, build it and maintain it well and your laughing.

My brother has a ZVH, and it's alright. But, it's not that great a gain over a standard CVH, and you get added problems of the oil not returning fast enough.

IMO, it's sh!te & a load of bollox. Me and my bro would never do another ZVH again, too much hassle, not enough gains.

Either stay CVH or go full Zetec.

Well I don't really want to go full Zetec so I'll just stay with the CVH... suit's me, it costs less. :lol:

I WAS being sarcastic. :nerner:

I just thought it might be an easy way to make a 2L CVH, but it sounds like it introduces problems that make it a better option to stick with the original block and get that reworked instead.

Mark, when doing the ZVH, not all the oilways mate, so you have to block them off, so the oil comes into the head, and doesn't return fast enough.

It blows it all out the rocker cover, and creates the need for a oil breather tank.

Then you have to redo your sump/block for another oil return, but the pipes clog easily (as like all oil breathers do) so the oil doesn't get back down.

AND after my brother doing it for years, he's never noticed a big enough gain over a stadnard CVH block (except they are stronger) to warrant the effort put in.
