i have a SOVP44 and my buddie has a HOVP44. we both have the edge drag box. his truck has alot more timing clatter than mine. do the HO's have more timing from the factory? or is my box not adding the timing like it should be?
 
Different valve seats in the head also, "powdered metal" , aka drop out style lol.
