Does a 99 Denali come with 096 Vortec heads?

Looking to put Vortec heads on my sbc 350 and have the opportunity to buy a whole running and driving Denali for 400$ wanted to know if the 096 heads came on this truck

People will tell you there is a difference between 062 and 906s but I dont think its anything that makes any difference.

I have heard multiple engine builders say about half of all vortec heads that they see are cracked between the middle exhaust ports, regardless of casting #

So basically saying I should just buy new?

that is an L31 engine so it has a roller cam and the 906 vortec heads. I have the 906 heads on my SBC and they work great. The difference between the 062 and 906 is the vavle seats are hardened on the 906 making them more difficult to rework to put in larger valves.

Like the guy above said the heads will most likely be cracked is that true? If I take them off a running motor?

At the risk of putting words in his mouth. I think he was just pointing out that difference between 062 and 906 is negligible. And yes, they were known to crack. Lots of SBC heads, Vortec and otherwise, are running around with minor cracks. $400 for a running Vortec is reasonable.

I have 2 sets of 906 heads and neither are cracked, both sets I bought used

I can get the whole truck for 400. I just might do it

I would do it, you can snag the engine and still get a couple of hundred scrapping the rest of the truck

Block may be a no go depending on your intended use.

Many did not come with a mechanical fuel pump but not all. I would say a 99 probably didnt
