14102193 ?

I just got back from the junkyard with the 14102193 vortec heads, I couldn't find any 906's or 062's so I settled for these, but all I can find on them is that they are either 305 or 350 heads with 1.94-1.50's. Is there anyway to distiguish between 305 and 350 heads. Also will these flow the same as the 906's and 062's? Thanks

193 casting is the tbi 350

the diff between 305 and 350 is the gap between the chambers, also intake valves on 305 are 1.880"

Re: 14102193 ?

I dont think those are Vortec heads, Vortecs came out much later than 1987

14102193...87-up...305/350......1.94"/1.5" valves

The "gap between the chambers" is the same on a 350 and a 305. Basically its the 58cc combustion chamber(on 305 heads) vs 64-76cc chambers on 350 heads, with slightly different runners sizes.

If they are TBI heads, they wont flow for crap!

They are vortecs, centbolt valve covers and the 8-bolt intake. Came off a 97 TBI chevy truck. Why wont they flow for crap if they are TBI, I thought the 906's and 062's were the best once you can get, and they both came of TBI vehicles.

Re: 14102193 ?

Vortec engines used a CPI with a plastic upper intake and a spider injector setup.

Are you sure about that casting number...From what I understand, there are only 3 different casting numbers..
10239906 - the head to avoid due to the pressed in exhaust seat which kills flow in the low-mid range of valve lifr

12558060/12558062 - The desirable heads. The 060 cast number is the actual first casting, and can be turned into either the 062 or 906 dependant of application. If it retains the 060 casting number, then it has a few minor cosmetic differences from the 062, but the flow rates are identical. The 906 head wasnt a long produced head though.

This is from info I gathered while doing my Vortec build up, so I cant vouch for total accuracy, but I can vouch that the casting number you have is NOT a vortec head.

Re: 14102193 ?

I know for a fact it is a Vortec Head, GM never produced a centerbolt, 8-bolt intake head that wasn't a vortec.

Re: 14102193 ?

alright, a vortect head or not....forget casting numbers does it have an egr crossover? no vortec heads EVER had a crossover

and sweet, i work with cylinder heads for a living, the gap between chambers on a 305 is different than a 350. also, 305 didnt come with 1.94 intake valves

Re: 14102193 ?

Also, if you look on the head in the front, there should be 3 triangles if it is a true vortec head.

I didnt say the head you have isnt a vortec, just the casting number you posted up.

Better yet..[click here

You've got that backwards. 062 had the 3 triangles and 906 has the hump. Other than that I agree with everything you said. lol
We've got one of each out in the shop so i could double check..


Here's the 520 305 vortec casting mark


As far as I know there are only 3 different Vortec v8 casting numbers:520 (305) 062,906 (350)

backwards?? huh....

i built two sets of 906 that have the hump...

you know what i did find out? one set had factory seats, the other set did not. this was the first set of 906s that ive seen without seats

im thinkin that this guy got some heads that someone converted the intake studs on. we have a kit at work for it, bolts on the intake side and you drill and tap the new holes for the vortec intake

Its possible they could be refered to as a vortec head, but they are definatly not the same "Vortec" head everyone wants.....

And you also wouldnt want to go on telling people you have Vortec heads, because people now days are educated enough to know what to look for and will know your lying, because the term Vortec head refers to one that makes more power and has a 906 or 062 casting number.

So for all intents and purposes, you do not have what people refer to as Vortec heads

Back when Vortec heads were not legal at our local dirt track the stupid ass no nothing tech man almost ate fist when he accused one driver of having Vortecs.
They were just regular ol POS Tbi heads.

Re: 14102193 ?

Corvette heads were shi@t. My buddy had a choice between a set of aluminum corvette
heads(centerbolt) and vortecs The vortecs were the lump type with the hardened exh.
seat. well the vortecs fowed 229 intake the vette heads flowed 190. even after porting
(he picked the vette heads for weight savings) they didn't outflow the vortecs. The exh.
side would've been another story the vortecs flowed 140's (poor) cause of the seat.
