I hate to be that guy...not really. There is nothing wrong with that. Lol the fact that you are in the guts and don't known that is descriptive. A cam upgrade, a few sizes bigger! Never change a cam without proper supporting components, it's the heart and brain of the engine. Chrome molly pushrods!!! Always, crane,comp,jessel, t&d are all good like most. If one cuts corners or is cheep in this hobby, the inevitable is on its way to your garage. If your valve train did that you would know it before looking for the 7 sixteenth. As I say friends GOOGLE is not experiencing, it's ignorance.
