Hunting for 062 Vortec heads...

The local pick and pull sells iron heads without cams all day long for less than $90.00 a set. They are constantly replacing their stock with fresh vehicles. This place is like a play ground. I've never been dissapointed yet. Well my next mission is to obtain a set of 062 Vortec iron heads. I'm not sure what all models and years of cars/trucks that these came on.

Does anybody have a good resource to locate this information so that I know what I'm looking for the next time (Friday) that I go to the yard?


Thanks,
Roach

A safe bet is any 5.7L (350ci, not the 5.0L/305) 96-98 C/K Truck, Suburban, Tahoe/Yukon, Escalade or Van. Basically all the full size vehicles. It gets a little iffy from 99-00, As I've heard of 1999 and 2000 MY trucks that are the 1988-98 Old Body Style.

I've never seen the title to one of these monsters in real life, so I'd hedge my bets on the 96-98. GM had already moved to the GM800 platform for MY 1999 and those trucks are distinctly different and have a completely different engine under the hood, although it still kept the "Vortec" moniker.

If I was looking for Vortecs, I'd just buy a set of RHS heads.

X2^^ the aftermarket Vortecs are much better. Thick castings, better flow & cooling, already setup for more lift.>> http://www.competitionproducts.com/C...products/1262/

I get non-cracked Vortecs off of craigslist for $100 or less for the set. I've had a few sets (just got rid of one and have another on the shelf right now). Most of the time its the 906 casting, which is the better casting anyway.

Some people try to sell them on there for outrageous prices like $250 a set... And as far as I know they are still trying to sell them...

I suggest trying places other than yards as most of the work is already done for you, and I wouldn't look to pay more than $150 for a set of any factory equipped sbc heads, they're simply not worth more than that when you can get a complete ready to bolt on set of heads from EQ, RHS, Dart, etc. for their relatively low prices.

I saw a bone stock LT1 listed for $2500 yesterday... And when you can buy a 6.0L for less than a grand why would anyone even bother listing it at that price?

X2-X2, once you get done with the machine work and parts cost involed in rebuilding these heads you will have only saved about 200.00 over what it would cost you to buy a set of RHS pro tokers, and trust me that extra 200.00 will be well spent considering i would put money on it that you would get 20hp/tq more out of them on the same engine. that's 1hp/tq for every 10.00 spent that is an incrediable ratio.

I am not 100% sure but if you can actually look at the front of the head casting I think all 062's had 3 trinagle humps cast into them that look like saw teeth.

Where did you get that information??


According to what I've researched about them...All the articles I've read have said to avoid the 906 castings... I've read that same info in several articles.

Here's an excerpt from Chevy High Performance

For you junkyard hunters, be forewarned that some - and 1-ton trucks came with Vortec heads equipped with a specially hardened exhaust seat that kills low- and mid-lift flow. Casting number 10239906 should be avoided. "



Regarding the possibility of going with a set of RHS heads. I know their better heads but the price is far more than the cost of a set of Heads from the yard. But I did look those over really really good. I'd love a set of those no doubt but the truth is that for my budget the Vortec heads from the yard will have to do if I want to be able to afford a cam and intake as well. My expendable income comes in lumps of $200-$300 at a time.

Now that is a pretty convincing argument you have there.


The more I think about it the more I convince myself that the RHS heads are the way to go.

That's what I've read about them as well.

This Info has been disproved. There is a machined lip where the seat was installed that hurt flow in the throat, bowl area. The Exhaust seat is actually better and the lip can be smoothed out very easily. These Heads do come from harder working engines that may have a larger chance of being cracked.

I've only had one cracked set of Vortec heads- 062 castings actaully (my only 062 set), but I've only had about a half a dozen set of Vortecs so who knows...

They can be a great head, but as noted plan on dropping another $400 right off the bat for machine work- milling, valve job, rocker studs and guide plates. All of that is already done with a set of RHS heads.

I know I'll get flamed for this but it appears getting a bare set of ProComp heads may not be a bad option either.
