I have a '91 Mustang with an Mass Air Cobra Intake MSD 6A ignition and Hooker Headers. I am looking into getting a B303 Cam which is 224/224 .480/.480. I am worried about floating a valve. But I dnt wanna spend money on Valve springs unless I really need them. Can someone tell me what I need to do as far as new valves?

Thanks

 

B-303 cam? your car will take it no prob. smallest one they make. no real worries. you could put the B cam in a stock 5.0 with close to no mods. i'm pretty sure you'll be just fine.
