ok, thank you. Not to sound dumb, but I thought vortecs were like 72ccs? If I don't have open headers and since there'll be a load, would that bring everything down cuz right now I'm looking at about 311 max hp and 318 max torque since valves will float at 5500 rpm, right? Sorry, just trying to figure out how to read this. Hmmmm, that's not a lot of torque. Thanks!

edit: i guess the vortec heads are 64cc. . . . .wonder where I got 72?. . . .

Got the head specks here
