Question

What's a good way to really clean a set of heads at home besides just washing them down with gasoline using a brush and gasket scraper??

Has anybody ever put them on the BBQ Grill and cooked them for several hours at say 400 degrees, then clean heck outta them after they cool down??

Or should I just spray them down real good with a couple a cans of Easy-Off Oven cleaner and wrap them up in some lawn baggies and let them sit for a week, then scrub them down real good??

I'm gonna start working on a set of -601 heads for my 283 just for the fun of it and want them clean before I start grinding on them sorta thing, that's all..

I just didn't want to cart them off to the Machine Shop for a "hot-tanking", and then bring them back home, grind on them and then have to take them back for a valve job..

PS., is it OK to cut the lightweight, -601's, .030" to get them down around 53 or so cc's so I can be very close to 10 to 1 CR. using stock bore, four valve notch, flat-top pistons??

Please, don't use gasoline. Try mineral spirits or cleaning solvent if you can find it.

I like the idea of the oven cleaner.

As a final wash, I have a siphon type sandblaster. I just stick the pickup tube in a bucket of hot soapy water and let 'er rip, then rinse with straight hot water.

Definatley no on the BBQ grill. I'm not too sure about oven cleaner for a week either. I'd be afraid it would etch the valve seats and guides. I don't know why you would be concerned about two trips to the shop. A hot tank followed by sandblasting is the best way to clean up heads. The only do-it-yourself method I can recommend is to use a wire brush and a can of spray carberator cleaner to remove carbon followed by a good wash with solvent. Then follow that with a hot-water rinse and blow dry. Personally, a trip to the shop would be worth the price of elbo grease and a couple of cans of carb cleaner.

I hear you, I guess I'm just getting lazy in my, er, -- a, heck, I already am LAZY b/c I don't even have my big engine in my car yet and here I want to start playing with another!!

Boy, talk about stupidity!!!

NOTE, NOTE!!! I should have my new rear pdqCBB 11.75" rotor caliper brackets done shortly so I can install them and finally put the two extra leafs on each side in the back and be totally done with the suspension and brakes except for setting my front coil height!!

Motor in and then I think I will go with a 100 percent W/D/T glasspack exhaust!!! Three per side as long as I can get them to fit!!

PS., I did have a bad curb binder on my son's mountain bike a week ago last Thursday and had to lay around on the floor for two day's!! And my left palm still hasn't healed up as hasn't my right knee!! Boy, that was stupid on my part not leaning to the left!!!

I gotta get healed up, get my Buddy to bring his Buddy's Cherry-picker over AND also mulch the scrubs and flowers with about two pick-up loads of mulch..

I mouthing tooo much....

A cheap pressure washer with warm water will clean it so well it will start rusting almost immediately.

Cool

You might try your local paint store. A popular locally owned store here sells Varsol. Almost similiar to Saf-T-Kleen's solvent. I think it might be "A Variety of Solvents."

Bring your own container, cheaper by the bulk size.

While the heads are being done at the shop, I'd ask him about installing hardened seats for unleaded fuel.

That's a good idea Everett!

Never thought of bulk solvent. I used to use Stoddard Solvent on the RR years ago to wash down the Tamper I ran but I don't know where they got it??

As for Saf-T-Kleen's small parts cleaning solvent, it's hard to say what it is b/c I helped write up an exemption so they could use recycled, slightly HAP containing stuff in their rental paint spray gun units b/c the stuff that met our state's vapor pressure spec. couldn't clean hard paint off the spray guns.

I use the "Oil Eater" brand degreaser sold at Costco with excellent results.
It's not to expensive and works well in my parts washer.
Hoses right off with water and hasn't hurt the plant's next to the driveway - yet ("non-toxic/biodegradable").
I use this in place of most solvents now.

(edit) Well He11 - 'googled' them and they've got a web-site... (doesn't everybody now)-
http://www.oileater.com/
Hope this helps

I primarily use castrol super clean for cleaning grungy parts. Get a cheap plastic tub (like the storage containers at walmart...they are about $5), and use 10 gallons of hot tap water and 1 gallon of super clean. In a couple of hours there wont even be any paint left on them [img]graemlins/thumbsup.gif[/img]

I've been using carb cleaner from Wal-Mart. It's .78 cents a can and is some really powerful stuff. It will take paint off right along with the grease and grim. You'll need good ventilation because the fumes are horrible. I can't remember the exact name (at work or else I'd look) but look for a black can. I've bought all they've had on the shelf several times. Twenty bucks will get you 25 cans.

If you use the castrol super clean, remember 2 things. 1) Do not use it to clean aluminum or cad plated parts that your care about their appearance! 2) Make sure you wear rubber gloves, like dishwashing gloves. That stuff is as bad or worse than any degreaser, gasoline, solvent, etc. on your skin.

Also, as was stated above, the walmart carb cleaner ($0.78/can) is a wonderful cleaner/degreaser. I also buy the stuff by the case [img]graemlins/thumbsup.gif[/img]
