I bought a pullout ZZ4 cam which i used in my 305 for 500 miles or less. cam looks great no damage or imperfections. i swapped in a 350 and used a bigger cam so i have no need for this anymore. its a great cam for a 305 or 350 and is computer friendly. i paid 130 for it originally so ill let it go for 85 shipped.
only way to manage this with any stock head would be either having the guide bosses cut down on the valves to make clearance or you could buy +.050 retainers like i did and itll clear fine. if you want id sell the springs and retainers i used with this cam. also have same mileage and are brand new. for the matching springs and retainers itd be an extra 110 for those shipped.
