TBI to Vortec I own a 1990 Chevrolet C1500 with a 350 TBI. I have been told from a few people that I should switch out my TBI heads to Vortec heads. Has anyone done this, because I really don't want to do much modification. I don't really have the expertise at this point to take on anything to big, but if it is just a matter of changing gaskets and bolts, I can do that. What all would I have to do.
You'll also need the Vortec/TBI intake manifold found here.

This is correct. The heads will bolt on and give a nice compression bump. You will need the vortec intake TBI manifold. Also a good idea to get a fuel pressure regulator and a computer tune esp. if you put a cam in it while it was out. That's always a good idea. The stock vortec springs are max about .470 lift. Anything higher than that and you will need bettre springs and screw-in studs.

I have a 91 S-10 with the 4.3 and have cosidered doing the vortec heads on it and that was one of my questions. I have headman headers and they will also work with the vortec. I'm 99% sure the same goes for the 350. When you call summit or whoever tell them what your doing and they should be able to tell you.

Verdad Gallardo not trying to ***** your thread with a sales pitch, but I have a fresh rebuilt set of the 193 tbi heads from the machine shop i would sell for what i have in them ($200+shipping) if you get in a bind. Im not using them as i just put a carb'd crate motor in my 88. They dont have a rep for being a good flowing head, but for my bone stock beater, they work fine. Aslo got a holley street dominator intake for the centerbolt heads too.

Make sure you find someone willing to make you a mail order tune for your proposed changes before you go ahead with them unless you want to get a dynotune. I could not find anyone to tune my TBI Vortec setup and ended up getting a Edelbrock Performer Vortec Carb manifold, and a edelbrock performer carb. Which I was quite happy with and I'm glad I went that route. I was getting 26mpg on the highway with a 6 speed, 383, Vortec heads, and performer carb and that's including some spirited driving!
