B308 engine head cleaning questions

GM 54-Degree V6 engine - Wikipedia, the free encyclopedia

This article says my engine head is aluminum. Is it safe to clean with baking soda? Also, how do I take the valves out? I want to make this clean as possible using household items I do not have a high pressure hose

If anyone tells me a good tip that is sure fire, I will make a instructional YouTube video for the forums with before and after

There should be lots of how-to videos and articles about how to get the keepers out of the upper spring seat to get the valves out. I made this album a looooong time ago when I had to replace valves in my 900 and made this compressor from stuff laying around the house, sounds like you're into that sort of thing.

As for cleaning, you can use pretty much anything - why baking soda? It's not a degreaser or anything. Acetone, brake cleaner, Simple Green, Greased Lighening, dish washing detergent (Dawn is actually a really really good degreaser, you don't need a bunch.)

Don't use anything abrasive on the mating surface that bolts to the block that might scratch it, like a wire brush or steel wool, but scotchbrite pads work well.

You should be able to submerge that in a 5-gallon bucket with degreaser and let it soak and start to break down the junk that's all over it, then scrub it up.

(I'm assuming you just want to do this to learn - if you're going to re-assemble or try to sell them, most engine shops will hot tank heads for low money, like $30-$50 for the pair probably and they will be sparkling. It's a heated solvent bath of some really really nasty stuff that dissolves all the carbon and grease buildup.)

Thanks! I used dawn but I just did a soft clean. I thought it was ok, until I looked at what they looked like brand new. I had no idea. I am on school for auto mechanics and am taking apart me saab, parting it out, and learning slowly but surely so I can open up my own shop one day. Thanks for the link. I'll post here my results I'm gonna do it tonight.

I'd drop it off at a machine shop, and ask them to bake and plane it.
$100, tops, and you'll have a "brand new" head.

No matter how clean it is, it'll still need to be planed before you bolt it back up.
most shops will clean it before they deck it

I read that if you put it in the oven at 500 degrees with shim stock and bolt it to a board tightly an cool it for 5 hours it will be planed. I'm going to soak it on degreaser soap and baking soda for an hour, take a old credit card to it and see what happens. Then I will remove the valves

Um, no. Planing a head means milling it flat. The machine shop will actually remove material. Only needs to be done if the head is warped, and the shop should be able to tell. Most heads have some extra material cast in from the factory to allow some removal. This might also have to be done on the engine block as well to clean up the mating surface, like if it is pitted.

The relaxing ovens are used if the head is warped from being overheated. It's not to straighten the face that mates to the block, it's so that the cam journals don't bind. And yes, it's held at temperature for a few hours, and you do shim under the high spots, but you have to be able to accurately measure how warped it is and Sun the appropriate thickness. Usually done with a granite surface plate and measuring equipment you likely don't have available anyway.

Then the deck surface is machined so there is a fresh surface for the head gasket to seal to.

This is after baking soda, soap, and a credit card.
