Experts and Know-it-alls welcome..

Good choice for heads. A good cam would be Hughesengines. Com 318 whiplash cam. Go to their website and view the videos of cars running the cam. Sounds damn near like a funny car and performs well. They also have a tech article on intake manifold fitting and sealing. I would buy the cam kit with lifters. But not the adjustable rocker arms. Use the stamped steel stock ones, used,new or what you got. Grind bananna grooves in the bottom of the shafts across the oil hole where the inside bottom of the rocker arms ride. Make sure shafts are installed right side up facing the right direction. Take pictures of the before you disassemble them off your old heads, mark rocker arm order so arms go back on the shaft the order they were on. Those guy at Hughes engines will try to sell you everything under the sun, especially Dave Hughes. Buy just what you want. They talk a good game, but also their parts are cutting edge and top quality.
