What is about the max lift you can safely go on the 4.9? Also, are these roller motors? Are the cams hydraulic? I was looking at the Clifford performance website, because they are just about the only people I could find with any aftermarket parts for the 4.9, and they have a wide variety of cams. I want to get headers, either clifford or hooker (who do you recommend?), an intake and a cam. I also thought about having the stock head ported and adding an ignition. I know you don't recommend this, I've already asked, but since you know just about everything about this engine and I respect your thoughts and opinions, I thought I'd ask. Thanks for the suggestions.
