Can't knock a ZVH though, had them in 2 of my Escorts and they both flew

that's why you can knock them

to pay money to make alterations to replace a head which comes with the engine for one which unless extensively ported does not come close seems odd.
Ive driven a number of ZVH's and don't think they are a touch on a well built CVH which revs a lot nicer imho
CVH or Zetec are the only choices imho,
