Randy....I was looking at your signature and I see your engine is a 448(.040 over)..

my 499 was a 448 and had StageVI heads, non maxwedge w/2.14 intakes...of course those heads have raised ports...and compared to maxwedge openings and runner size, they were tiny...but yet with a .557 cam, the Duster would rock...consistant 10.0 and occasional dip into the 9's..and that was when it weighed 3300lbs gross..

so what Im saying now after looking at your info, money probably better spent on the porting and flow correction, then get a cam specked to your flow numbers...

or just can the heads and get bigger stuff...LOL
