Best next upgrade?

I'd skip over the 8 3/4 and go straight to the D60.... (Same money more bang for the buck..)
And now you're going to be ready for anything you through at it . Good headers hands down...
Then.. my personal bang for the buck:
Build 360 stroker...
4 spread.....
555 nito's....
Oh ya if you got big ones..
DUAL QUAD TUNNEL RAM....!!!!... :thumbsup:
