I have a guy locally trying to sell me some heads, he knows that im looking for a good set of vortec cylender heads, he contacs me saying that he has some that hes had for about a year now trying to sell. Anyways i go and check them out, assymbled, cleaned, but he is offereing free hottanking, but it has a casting number 14102193 , with acc holes, but it has 2 small parallel lines on it. MorTec says they are 87+ TBI heads He is very convincing that they came off of a 96 chevy 1500 truck with a 350. Only wants $200 I can find them on Ebay for the same price. BTW is it worth to port and polish them like anyother head, and then sending them off to be machined?

Those heads are total junk and not worth $200. Those are probally some of the worst heads for a performance application made.

All vortecs have a heart shap combustion chamber and only have 4 holes per head on the intake side.

193 came on 350 trucks 87-95 only

My dads 96 G30 van came factory equipped with TBI and those 193 heads. I was expecting it to have Vortecs when he bought it, but was dissappointed.

I wouldn't pay $0.25 for those heads regardless of the machine work, or port work done to them. The are absolute garbage (in terms of flow) and there is nothing that can be done to fix the major flaw they have....the swirl ports. you can port them, but they still won't flow for crap. They are not Vortec heads, and you are getting ripped off whether the seller is aware of it or not.

thats kind of ironic i just looked at a set of thoses same heads that the owner thought were vortecs but were 14102193, luckly i knew what vortecs look like and didnt get them and he only wanted 100 for them, why do people think that any 87 later heads are the great vortec heads

As stated, Mortec is correct.
You missed the most critical "Vortec"attribute.

Raised port locations. But who's counting?

And 193 heads are 350 TBI, period, not limited to trucks.

Center-bolt valve covers theres alot of stupid people out there.

Between that and the fact that they are on a truck.

Some of the confusion may come from the fact that the same guys that designed the LT1/LT4, 'swirl port' and 'vortec' heads. The swirl port were also referred to as vortec heads early on, though the later named Vortec engine more appropriately shared it's name with the '062' and '906' casting l31 'vortec' heads which were the major source of it's improved power and economy.

The '906' casting has larger intake runners and better performance as far as factory castings are concerned, IIRC.

whoa... this is an old thread....
