From prior Forum information:
If you plan on using the 422 cam, you will need dual valve springs and retainers, you will also need your heads machined to fit the dual valve springs. When going to an aftermarket cam, the base circle is .050″ smaller than stock so they can get the extra lift and still fit through the cam bearings. By math you need .050″ longer rods which would be 5.525″, but it doesn’t always work like that. To many thing effect it which is why you should measure, If you cant or don’t know how, most people normally go with 5.550″ unless the heads are milled. If you’ve had your heads milled, you’ll have to compensate for the thickness in material that was removed from the bottom of your head. Smith Bros Pushrods will have the right 5.550 inch length.
