It would be my guess though that the exhaust valves will need to be replaced.

I did, $150 to check them out, so if they are bad and I don't want to move forward its $150 down the toilet.

Wow 150 thats crazy money. We get 50-75.00 to check a set of heads.

Looks like you are in Cali too, so I am wondering what does that entail for $50 bucks? In my case they get hot tanked and washed and magnafluxed and disassembled.

Re: Restoring Rusty
 
In our shop the heads get disassembled and degreased. Valves are cleaned and checked for wear. Good valves are refaced. the heads are magnufluxed for cracks and seats and guides are checked. Springs are checked for pressure. Then you get an estimate.

Not uncommon. I suspect lots of 97-2002 1/2 ton trucks on the road have hairline cracks like yours, but my machinist tells me the vast majority of them don't have symptoms. That said, I wouldn't put a dime in them, nor would he.

well after a quick trip out of town for some replacement Vortec heads turned out fruitless, I started on the OG Heads Autopsy, I should have know just from this text from the seller, after I asked him for some pictures and a part number since the ad had neither of those things, he wrote and I quote:

"If I'm going to worry about sending pictures and finding cast number I'm going to want more than $50 for the set"

he followed that up with a pic from 50 feet away of the heads with valve covers on them, LOL

Gotta Love Craigslist [/sarcasm]

alright so the Oirignal heads go on the work bench and the disassembly comences, getting these valves out was a bear as the retainers were gunked up in there for good, but The Greg persevered

I was blown away when I cleaned up the OG exhaust valve, it was in more better shape than his Vortec grandson, it could use a 30* Back Cut to remove the inner lip on the back of the valve wouldn't you say?

I is learnin that the intake valves always look a better than the exhaust, and this OG intake is no exception, nice metal

and here's how the magic happens, a quick tour of a state of the art valve cleaning facility

make sure you are using a high pressure fuel line and not some cheap vacuum hose, no just kidding it don't matter

alright you suffered enuff, so let me leave you with this Old Timmers Engine Tunning Trick from back in the day

lets say you got an engine that is running just right temp wise, or maybe a bit too cool, and you want her to run hotter, maybe even overheat, here's what works like a charm

pop one of them cylinder heads off real quick like and gently and carefully insert a small rock or pepple inside any of the water jackets / openings, I prefer somewhere closer to the back of the engine say between the #5 and #7 cylinders

took a pic of that peice next to a spark plug so you can see how big it needs to be

after a quick hug with a magnet turns out it was actually metal

lol that would be a breakdown of metal from various engine parts getting stuck and clogging passages.

that much foreign material is pretty scary.

spotted a beautiful 1999 Chevrolet Suburban down in the meadow by the creek. Judging from her antlers she couldn't have more than 247,472 miles on it, ha ha , so what's another 50,000 right? (Sometimes I thank the GM gods for Chevys being behind the times still using analog odometers, just imagine if it was digital we could not tell the mileage.)

someone already did some of the heavy lifting for me, since they took the passenger side head

pulling this head off made me remember my '97 Tahoe and how I dreaded working under the hood, just look at that mess

so after confirming the right GM part number 122558062 I locked her in my sights, took a deep breath and pulled the trigger, she was coming home with me today

don't mind the water in the valve train or the cylinder bores we had a storm for a few days and there were things under the hood with rain water in them that I knocked over climbing in and out of the engine bay

for reference I took pictures of both the intake and exhaust gaskers

FEL-PRO 98000 Intake Manifold Gasket

GM 12550033 Exhaust Manifold Gasket

(they would not allow me to keep the gaskets for free so that I would buy the same ones, no biggie, a picture's worth a thousand words)

the cashier made me pull the rockers off or he would charge me an additional $30 bucks

so here is the bill breakdown

$38.99 - Cast Iron Cylinder Head

$ .16 - Admission Tax

$ 4.99 - Core Charge

$ 3.41 - Environmental Fee

$ 3.79 - Tax

=====================

$51.34 TOTAL

first he quoted me like $65 bucks just for the head before all the BS fees with a ONE YEAR WARRANTY (I tried really hard not to laugh, and simply said No Thank You)

In case any of you may be considering such masochism I took a few notes on what I saw today in the yard that you may find useful:

1994 Chevrolet Suburban - 14102193 non Vortec Cylinder Heads

1995 Chevrolet Tahoe - 14102193 non Vortec Cylinder Heads

1997 Chevrolet Suburban - 10239906 Vortec Cylinder Heads

1999 Chevrolet Tahoe - 12558062 Vortec Cylinder Heads

1999 Chevrolet Suburban - 12558062 Vortec Cylinder Heads

so we start by removing the #1 Exhaust valve, yes she was running lean, but after the wire wheel treatment we see the same pitted condition as our original Vortec exhaust valves, so at least they are consistent

Gregski 03-16-2016 12:25 AM

Re: Restoring Rusty
 
4 Attachment(s)
then we removed the #1 Intake valve and we already expected the intake valves to be in better shape than the exhaust and this one was, it also was consistent with the first set of Vortec valves we already have, condition wise

Don't worry I aint gonna bore you with pics of all the valves, so we move on to the chambers, after all we gotta know if this head is good or is there yet another Pick N Pull expedition in our near future

for this process we move out to our [ahem] "Organic" Outdoor Facility

Pleased to report #1 chamber looks a good!

Pleased to report the second chamber, technically combustion chamber #3 passes with flying colors

alright 2 for 2, we're half way there, lets keep going

and the third chamber, properly referred to as cylinder #5 is good too, though it started out a bit weepy (no idea what the heck that was all about, maybe me shooting PB Blaster inadvertently in there when removing the vlave

Gregski 03-16-2016 12:45 AM

Re: Restoring Rusty
 
cool, 3 for 3 and no cracks, so how did the 4th one turn out?

I'll tell you all tomorrow, had to take the kid to piano practice, lol, and I'm so tired I really don't want to clean it right now cause it's late, it's been a long day, and I would just half @ss it, and I don't want to do that, so must rest
