yet another 318 build question........

so looking around and like i said I found a 68 340 intake that I am gonna get. I am starting to lean more towards the indy heads as they really seem like a bargin. Am I correct for thinking that the power levels I am looking for these heads will more or less be ideal right out of the box???? not sure on the cam or the gears as I am kinda looking at the Keisler 4speed auto..... I did completely gut the inside of the car last weekend and will be removing the engine and trans (and all other related parts) on my next weekend off. then it is on to body work........fun!!!!!
