Been looking for videos on measuring to find the correct pushrod length and stumbled on this guys videos. Watched his review of the stealth, RPM and trickflow head..all he says in every video is that he feels sorry for us mopar guys because none of these heads flow what something as big as a 440 needs..If he knows what he is talking about, i wont bother with anything besides the trickflow... but he seems like a possibly biased chevy guy..lol..i dont know, here is his trick flow video
