Not usually, but you always need to check. You do need to change/upgrade valve springs, retainers, determine correct pushrods length, etc. What heads are you using?

Your gonna have to check the PTV cleareance, and if you got stock valve springs, you need to sell those and get some stronger ones. The e7's springs are barely rated to .500 lift. Get your self some comp cams springs or trickflows. But be careful with the trickflows.

I've seen this swap done at least 50 times with No fitment issues.


Thought it read E cam. Couldn't tell you on the X cam
