I had some rear valve issues and decided it was time for an upgrade for the ol' boy and just ordered Screaming Eagle Racing Heads and Screaming Eagle High Compressions Pistons. It's already got a Screaming Eagle air flow system. Anyone else got into their engine like this or have suggestions on how to round this combo out better?

Sounds like you need to get the "required" pushrod kit too....
"Requires installation of Perfect Fit Pushrod Kit (-.050") P/N 18424-06."

I'm not an expert by any means, but if the 2001's had the 'W' cam stock, then
I would think you'd be extreemly detonation sensitive with high CR.
I would recommend consulting Hammer Performance or some other
experts about a cam change to match your combo.

good luck,
