So i have a 94 tbi and i want to do some work on it this winter over break. Right now im trying to decide between two options. First is putting on an edelbrock 3713 intake manifold and being done with it. I feel pretty confident i can do this in a couple days in my garage without breaking anything. My other option is to get a set of vortec heads and run them with an edelbrock 2114 manifold and tbi adaptor. I know going the second route will make a lot more power for about the same price and better support future mods. What i need to know is how much harder/ more likely to screw something up it will be if i decide to try to tackle swapping the heads. My mechanical experience includes taking the dash apart about 10 times and replacing the bumper. Also, will my 94 valve covers and exhaust manifolds fit the vortec heads or would i have to replace those as well?
