i just came up with enough money to afford the world torqer 305 heads. i want aluminum heads but cant find anything for a 305 besides teh LT1 heads but i have been told they require extensive modification. what are the best heads for the money on a 305? are the vortechs better than the world heads. i plan on buying a cam and new intake manifold also when i put the heads on. what would make good power but still be streetable? i love the sound of a nice lumpy cam. i already have 3.73 gears in the car. what would be a good combo for the money i want to go kind of radical. i plan on doing computer tuning also.
