I have the cat valvesprings/retainers and still have the crowers in my other motor and both do very well for me : )
springs and retainers
I have cat cams stage 2 (lift = .395) and my stock springs and retainers for about 30000miles. But I don't like the sound of my zetec (valve float) so i need to change the springs and retainers now. Is the ford racing a good choice ??
Another question, i have a 2003 ZX5 and one of my friend (2003 ZX3) troubles with the installation of the crower springs and retainers because they are cylindrical and the stock one are conical and the crower didnt fit. But another of my friend (2001 ZX3) didnt have any problem with it. Did Ford change something in the valvetrain between 2001-2003 ??
