OK so im putting my 455 back together got my new bad dog grooved cam bearings installed, my question would be break in. ie changed to a solid lifter cam my first on. On my last two cam break ins I made sure the car was ready to go gs113 and a gs105a i think. you know the one that said it pulls like a freight train. when the car started i put in gear an drove it for 1/2 an hour came home changed the oil and done no problems. However it has been recomended to me to pull the inner springs on the valves for the break in i believe im up in the 541 lift area now. wondering how anyone else has broke in solid lifter cams Thanks Don
