    Good kit

    I just installed these on my 2002 Roush with the stage 2 cams and have had no problems, the only thing I ran into was the seals that came with the valves didn't seat all the way down so i had to buy some other ones, great valve kit.

    still waiting

    I ordered this kit with my cam gears and other parts. My other parts came in but its been a week since then and still no sign of the parts. This is the first time anything went wrong from american muscle and I've been a customer for years. Point being if you don't want to wait until your mustang is a classic order the kit elsewhere
