take a look here and you should get the idea

Theres a lot of mixed views on ZVH's, personally i would say if you don't have a very deep pocket then stick with a CVH.

And for your second question, - EFI all day long. MFI is wank

 

thanks think i will stick with the cvh then but u say put the efi on it wot about the cam because im going to recon my spare head and the cam thats in is f@@ked i wont it all done and ready to drop on so dont wont to take mine out the one im running

 

The cams are near on all the same, the EFI cam from Ford has very slight power gains over the one fitted to the MFI cars but they are both interchangable

 

SafeChav I know this too but do you know what is the difference between them? higher lift? longer open period?

 

I can't be anymore specific than that im afraid

 

I have one and I can't even check it for wear as I have no values
P.S. Haynes again says nothing about different cam or anything on EFI engines

 

You should be able to tell if theres wear or not as the lifters don't sit directly over the cam lobes, usually theres still little black segments where the protective coating has never been touched, if there isn't or theres pitting on the lobes then its probably knackered.

Second hand cams are a bit of a no no to be honest with you

 

every new cam becomes second hand in day or two....

Anyway, I've never seen original ford cam as a new... so can't compare

 

They don't wear THAT quick. My orion is approaching 110k on its original cam..........

Ive got a brand new Ford cam, got it for about £50, that lasted a few hours (was my own fault ) beyind repair now

 

What did you do wrong? I want to learn from others mistakes

 

I was experimenting around, nothing that should ever happen from normal use

All the lobes are still as new apart from the one that has a MASSIVE groove down it
