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.
i was just stating the fact that a cvh head will easily flow over 330bhp so if he dont want more power than that why bother with the extra cost of building 16v haed and cams

i was just stating the fact that a cvh head will easily flow over 330bhp so if he dont want more power than that why bother with the extra cost of building 16v haed and cams I mean for a drivable road car. He's already got the managment etc, and could get some manifold adapter plates easily for less than the cost of repairing his cvh head...
He's already stated he's looking at 250 quid to sort his cvh head due to a problem with the valve guides. Not think it'd be easier to just use the 16v head? I just don't see the point of going through the hard part then using the head that flows less and requires some work to repair it..
Anyways, not a dig at you or anything mate, I do appriciate your car makes really good power and impressively it's still a 1600 CVH... But if it was me, and I was in his position I'd be using the 16v head right now.

Saying that, we're here as we're into Fords so wasting cash should be something we're used to

16v head all the way stu. Before i sold the s2 i had me hands on a 2.1 bottome end.
Advice from Jano oddkidd was, get a 16v head on it. Why would you want to fit a cvh on it??
Got to admit, it was a valid point dude

Complete garbage being posted. My NMS head flows significantly more than a std Zetec head. It's not just about airflow figures, it's about to do with combustion chamber design, swirl, squish... The Zetec head is not designed for performance. Its very costly to have it ported properly. As a 16v engine, it's really pretty lame.
If the CVH head you have is done properly, then it will do over 350hp no bother.

so in conclusion...yes you have the right block PMSL
im going the full zetec route and yes its VERY expensive
as you have said already...as you have the parts for the ZVH go that route. The reason i went full on zetec is due to the fact that im building the engine up and not using the engine in my car whatsoever. my aim was 300-320hp, for a cvh i would need a fairly expensive head...but i knew with a standard zetec head, cams, valves etc etc i could do it no problem
stu, out of curiosity what sort of power do you think you will hit?

Dont really know mate
Going on how it was before (5k rev limit and 1bar boost) I was still pulling away from a 280bhp escos like it was going backwards
With rev limit removed and 2 bar, your guess is as good as mine

Fact =
It will cost around £1k to have a decent CVH head with components fitted like twin springs, big valves, port polish, solid lifters, camshaft, etc etc...
Say for figures you can get 330bhp with it costing £1k.
A Std Zetec head with std cams and lifters etc.. can flow the same without any mods. (Tried and tested)
So why spend X amount on a CVH head when you can buy a 2L Zetec head from the breakers for £50. Take it apart, clean, check and put back together for less than £100
Now instead of spending all that money on a Restrictive CVH head you could spend the $$$ on decent rods and pistons for the Zetec Block.
Use the std head and you will have 300+bhp without even running very high boost like the ickle 1600cvh's have to, to get power.

Took new bottom end to nms today
Block being attacked on Monday, shud be in by end of week, then just needs Karl to finish his bit of expertise on the laptop
Then will be run in on mineral oil for 1k (while running 1.5bar) then back to nms for the boost to peak at 2bar
CANT FOOOOKIN WAIT

are u comparing a pentroof design with a hemi??? u r joking right?
squish on CVH? only on the heart shaped cc of head's (and its not that good)
can u compare the very little swirl from the CVH with the tumble swirl of ANY pentroof 4v design....
sorry mate, u re so wrong!!

Secondly... Your saying a cvh head for £700 can flow X amount. Its still £600 more than a Zetec head that can flow more than what you claim out of a std CVH head for less money..
So your head (On your car) cost £700 and is still std is that what your saying?
Where did the £700 go to? A cam and lifters dont cost that much
I have a std head on one of my own cars and it will not flow 330bhp FACT!!!! at least not without raming LOADS of boost into it which id rather not do...
Just dont make sense

Jano, i think Stuart means his head has std valves, but is modded elsewhere.
I'd possibly like a full 16v in the future, but i just couldn't live with the std head lol. I'd feel cheated if it wasnt using the 16v potential to it's fullest - which is what my 8v head is doing. 210hp at 11psi with a std cam isn't shy!
I'd like to use the I4 engine, as i think that's much better out of the box from what i've seen, and they sound like a 6!

for give me an haveng a blonde day 
this post sounds intresting ! so an i write in saying the 16v head has the best gas flow as standed than the 8v head and costs half the price to buy than the 8v head that has been fully gas flow with all goodys

Jano_OddKidd is it me or u trying to say that for many posts now...? 
one thing you ppl are not understanding, is that zetec turbo's r the way to go, period...! for either monster bhp drag star's or daily use... with a zetec (for the same bhp as CVH) you get higher CR (good for drivebility, emissions, and fuel consump.), lower boost...
if I had an rst with a std engine, the first thing would be a 2L zetec totaly std, bolt the turbo and intake of the rst, tune it = 200bhp
if 250bhp was the goal, i'd only need a thicker head gasket to lower CR...
if 300bhp, forged rods and pistons, turbo, I/C...
and so on 'til 550+bhp!!!
