20v Valve Train Package - Custom made by Ferrera

[Bazda]

Hey Guys,

So we are planning on getting some custom 20v valve train package kits from Ferrera.
They have designed a kit for the blacktop head which allows 12mm lift.
The kit was designed for a guy in the USA who wanted the best of the best.

The valves have been specially designed with a special shaped tulip on the stems and a flat face on the valves.
Valve springs are based on the Moto GP bikes and good to 15k, comes with Titanium retainers.
Note: The oem retainers cant be used in this setup.

With mild porting the head flow is good for 280cfm plus! at 10.7mm lift.
A supertech package is only good to 250cfm.

Ferrera did extensive research and found in their design the valves would remain the stock size, this flowed the best at the high lift. Going over sized created shrouding issues at these lift levels. If the lift was under say 9mm then 1mm OS works better.

The complete set is $1600

Its about $600AUD more than a supertech valve train setup but its gona flow a whole heap more!
