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.

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?

Re: Restoring Rusty
Sir ... It looks like that one valve maybe bent.. Might want to either replace or check those lol.

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 |

Re: Restoring Rusty
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) |
