Looking for a decent stock pair of 4.3L cylinder heads. They will be going on a 1991 4.3L TBI engine. Looking for complete heads... something I can buy and bolt right on.

I have a set of vortec heads from a 96+ 4.3 I dont think the intake bolt holes are the same but they would make a nice upgrade. $50 obo

I'll keep it in mind, but I'd prefer to find something I can throw right on without modifying anything

I know a guy on here with the username teambeater who's trying to get rid of an entire motor, 4.3 out of something like a 93/94 blazer. It's a vortech, but not the same as those newer 96+ vortech motors.

I can make sure he gets you more details if you're interested.

I could do a whole motor on it, might be easier to pull the motor out complete then to try to swap heads with it in the truck, but I'm not a fan of the vortec 4.3's.

curious but why? assoposed to the TBI no less. i've had 3 vortec powered blazers, all were great, the one TBI i had was a dog

the early vortecs honestly seem like a pooch compared to the TBI to me, at least thats how it feels to me anyway

If the transmission isn't computer controlled, you could do this.

the heads off the earlier vortec are a direct bolt on to the tbi, its a pretty common mod for the sy ty guys. ill give you a great deal on either the motor ($150) or just the heads pm me if you interested. I want it out of my garage
