A friend of mine seems to think my bone stock 87 iroc would have vortec heads. He said I should check before changing them out for differnt ones. So did it come with vortec's??

The "Vortec" everyone talks about didn't come out until 96. So that would be a negative.

Mine has Vortec heads!!! I put them on there though. The heads on your car are referred to as Pre-Vortecs, but they are not the 96+ 062/906 Vortec heads designed after the LT1 head. Not all centerbolt heads are Vortecs. Easy way to tell is to take off the oil filler cap and look at the casting number, no need to pull the valvecover off

Tell him yeah sure it does, smile politely, and move on.

No point in arguing with someone who willfully chooses to remain ignorant over something that doesn't make the slightest difference. Him saying whatever, or all the arguing in the world, either one won't change what the heads ACTUALLY ARE.

If your car has TPI, DON'T change out the heads until you learn FROM THIS SITE what you really have.

Do explain...?

IF they are not 96-99 truck heads with an 062, 060, or 906 castng then they are not vortecs... unless they're 305 Vortecs?

Sorry, sorry, I meant Pre-Vortecs, thanks for pointing that out! Although calling them pre-vortecs isn't the best way either, it does give a certain time period, just before, rather than spitting out casting numbers most on here don't know. Just making it more simpler.....

Gotta be my favorite way of sliding the new "V" buzzword in there sideways without actually saying ANYTHING meaningful...

EVERY SBC head from before 96 fits that description. What a bucket of unvarnished steaming BS!! That sort of thing is so obviously designed to reel in the buzzword-seeking suckers it almost hurts to see it. And the pitiful thing is, the gullible fall for it.

ok...thats what I thought.

stealthroc89

I understand anything before 96 would be pre Vortec, but not all of them can be advertised as such to unknowing people like the 87-95 centerbolt heads can be. Pre Vortec doesn't sound too alluring anyways. You can say 87-95 heads and someone will ask if they're centerbolt, duh, ya. Then the typical "are they Vortecs" question is sure to follow because "all centerbolt heads are Vortecs". That myth is still alive and well, simply saying pre-Vortec puts all the information out there, not to say the word "Vortec". Sure you can be an a-hole and not pay them any attention, but then, the myth goes on...

Really?!?!??? And that would be because,,, .... ,,,, ... ,,,, .... ... ???

Think carefully before you tell us why "it can't".

All that does, is slide the buzzword in there, in a way that maintains plausible deniability and legal indeminty, while the gullible go right on and hear what they want to hear the same as they always have, do, and will forever.

Never underestimate the greed, or the stupidity, of humans. Remember, it takes 2 to make a Nigerian scam: the crook that sends the e-mail, and the nimrod that falls for it.

I already explained why and I understand what you're saying, but it isn't hurting anyone to say it here.

Your heads are as much vortecs as camelhumps are. Its just kind of misleading. I dont think anyone takes the kinds of people who say "pre-vortec" seriously so dont buy into that nomenclature - it's about as descriptive as "202" heads.

How so?

You haven't explained anything. All you did was mutter a little meaningless drivel about HEADS; but that's not what this thread is about.

It's about LIARS and BUZZWORDS.

What makes you so sure this new "V" word won't be as appealing to liars as the old familiar one? What about it makes liars suddenly not lie just because it's this new word? What's to stop LIARS from LYING?

Any liar can advertise ANYTHING as being ANYTHING. Which is precisely what "pre-Vortec" is: ALL heads (SBC that is) before "Vortecs", qualify as "pre-Vortec". Throwing that buzzword in there tells ABSOLUTELY NOTHING WHATSOEVER about ANY heads. There is NO LIMIT WHATSOEVER on what some liar can call a "pre-Vortec". It's A LIE, designed to put some lipstick on some pig and swindle a gullible sucker out of more money than whatever trash it REALLY is, is worth.

Meanwhile, the OP needs to let his friend live in his own little fantasy land, and keep his own feet firmly rooted in reality.

Well I was writing a long post to explain, but there was a blackout so I'll keep it short and simple since I'm on my phone. I think my 1st post may have been taken the wrong way. I have Vortec heads on my engine, I'm not saying I have 083 heads and they are Vortecs also. Once they fix the problem I'll edit the 1st post to clear up any confusion. Just heard they killed the power to my whole city to "save power", till 2am, yay. Oh well, time to work on the car for a while

No one confuses perimeter seal heads for Vortecs, with the valve covers off maybe, but whenever the average person see's the centerbolt valve covers they think Vortec. Why? Because they think all center bolt heads are Vortec heads. LT1's have center bolt valve covers, but they never ask if the heads are LT1 heads. It would be smarter since they at least were used in fbodys. The question is "does a 87 iroc have vortec heads", "not what heads does my 87 iroc have". The 081 heads came before Vortecs, thus giving us pre Vortec heads and yes all heads before. People may use the Vortec name to rip people off, I'm not doing that, nor do I plan to. Charels Manson watches TV, does that mean I shouldn't? How did this post go from heads to liars and buzzwords? I don't see any lies and pre Vortec isn't the new rage this year. It may not be a term you like, but it is used and used a lot to describe the early center bolt heads that were not Vortecs, just a way to separate the 2 in a way most people will understand.

"pre-vortec" is generally only used by people selling junk heads to get more money out of them. It's a way to separate Vortecs from non-Vortecs in a way that makes non-Vortec heads sound somewhat related and therefore a perhaps more affordable alternative. They could sell them as "Non-Vortecs"... but they dont, they advertise them as "Pre-Vortecs"... see the difference?

I've never known anyone to assume any centerbolt head is a vortec head. Vortec heads arent that common in comparison, ESPECIALLY in these cars. Even in a truck I still would say there are probably more swirl port 193/187 heads around than Vortecs. 083, 081, 193, 187, and 113 heads ARE common (well the 113s maybe not so much), and they're all centerbolts.

If I see a thirdgen with centerbolt heads I assume they're stock TPI or TBI heads from 87-92.

Really!!!?!?!?

How about THE OP'S FRIEND?

I think it's about time you give it a rest. Continuing to make a fool of yourself doesn't make you somehow "right".

stealthroc89

Why does he think that??

To be fair the op doesn't have perimeter bolt heads, they're center bolt lol

I disagree. Depending on his personality, the guy may just be ignorant to the truth. Educating him could then possibly keep others from getting poor information from him.
