Duane when you talk about oil starvation on no 4 main due to oil feeding rockers , if your using mag heads on a LA block and your feeding rockers via push rods and its not going via its regular route ,lifter gallery should hold more oil or would there be some slow down in the gallery's forcing oil to make its way into 4 main thus less chance of oil starvation on No 4 main.????? just thinking !
