Yep here we go......A David Baker UBV CVH Head

Congratulations to Sean Richardson for what we believe is one of the most powerful 2 valve per cylinder 4 pot engines in the UK. A ZVH (CVH head on a 2 litre Zetec bottom end) Sean had about 220 bhp when he came to me for one of my UBV (ultra big valve) CVH heads. The first dyno runs put that up to 300 bhp on the same boost but the turbo was causing lag and there were other problems to correct. The UBV head giving an extra 80 bhp though - which was nice. With a new roller bearing turbo and some induction and exhaust issues fixed it's just produced 428 bhp and 404 ft lbs at 28 psi boost on Engine Advantages rolling road. https://passionford.com/forum/viewtopic.php?t=223162

Assuming EA's rollers over-read by about 20%.. so that makes about 340hp..
