man I have actually been thinking about buying a 6.0 then having my 5.3 heads worked and put them on the 6.0 with a bigger cam and 3500 stall. just b/c I can get a 6.0 for just 400 more than those prc heads.. Ill let ya know, probably wont do much until it cools down.. If I can keep shaving my 1/8 mile time I may just spray it and call it good.
