Im sure someone has asked this question before but i cant seem to find the thread. I know some 95 and 96 5.0 f150 engines came with hydraulic roller lifters aposed to regular hydraulic lifters. How can i tell which i have without tearing apart the engine? I plan on putting a set of world jr.180 heads and a cam in it before december but i dont wanna to tear it apart for no reason as its my daily driver. Any help would be grately appreciated.

Thanks, Nick
