Hi all.
I am trying/about to buy a set of Ferrea valves for my 2.0 pinto head.
Ferrea don't list a part for the collets for this motor.

They do list a 2.0 16v zetec.

FORD ESCORT 2.0L (ZX2) (1999 - 2001) STEEL VALVE LOCKS
2.0L - DOHC ZETEC 16 Valve (ZX3)
Specifications: 5.5 mm. Radial Groove

The valves are F6219 and F6220.

FORD 2.0L (2.000 CC.) (1970 - 2012) INTAKE
2.0 L
Intake Valve
Head Diameter: 44.5mm
Stem Diameter: 8.02mm
Overall Length: 113mm
Tip Length: 5.07mm
References: 9" Flo


Has anyone fitted these valves and knows what collets they used?
Thanks for any help.
Darren.
