Getting the right quench


Recommended Posts

Ok... I discussed this before but now that I am ready to get my head gasket I've run into a problem.... well here's the background first...

400 block bored 40 over

Scat 9000 crank, 400 mains, internally balanced, 3.5 stroke for 6" rods

Scat 6" I beam rods w 7/16" bolts

Keith Black 194 pistons 10.7:1 w/ 64 cc heads

Canfield heads - 59.2 cc chambers

 

Also going with the Crane 114681 cam.. Thanks Grumpy!!

 

Now my problem, the deck is .018, so the SCE gasket I need is .032 to keep the quench within specs right?? The big problem is that the SCE copper gaskets require O rings. I would have to have the deck machined for those right?

 

I would not be able to afford that. So what other options are there???

look under, catalog, chevy head gaskets) I have been useing SOLID COPPER HEAD GASKETS for years with aluminum heads on iron blocks (WITHOUT (O)rings) If your surfaces are strait and true and you correctly install them they work fine, now keep in mind that you MUST run high concentrations of anti-freeze and an anode in the radiator sure does not hurt to prevent electrolosis from causeing problems but I have never yet lost a head gasket and that includes nitrous use on several engines. now they sure are not your only option but they are a good one. btw I totally clean and degrease the block deck and head surfaces then spray the head gasket wet with COPPER COAT GASKET SPRAY then install them tacky wet and torque them down in 5LB stages to factory spec http://www.jcwhitney.com/productnoitem.jhtml?CATID=5131&BQ=jcw2 I6993.gifI6990.gif RADIATOR CORROSION INHIBITOR Prevents overheated radiators caused by rust, scale and corrosion. Save money on needless flushing, repairs, anti-freeze changes, special additives! Zinc anode slips in radiator filler neck and neutralizes rust/corrosion-causing chemicals. Lasts for years. NOTE: Not for radiators with plastic tanks. http://www.pjhbrands.com/vht/coppergasketcement.htm

Hey grumpy...

I need a steel shim gasket to get my quench right and while shopping around I notice Felpro sells a very low cost copper "Headsaver" gasket that is .020 thick. It is advertised to be used with a normal Fel pro gasket to add thickness for when stock replacement heads have to be cut a lot. I am considering using these as my gasket. the thickness is right and maybe they won't leak as much as steel? any thoughts, experiences, massive lists of links on the subject?

Thanks for your expertise.

sorry

Ive always use the SCE copper head gaskets and have no experiance with that gasket your refering too. but useing a single copper head gasket should work just fine, useing BOTH a steel shim and a copper head gasket sounds like a great way to get leaks to me!

Thanks for the info.

 

I think I'm gonna try using the "headsaver" copper gasket on its own. The thickness is right, the price is actually cheaper than steel shim, and hopefully it'll seal better than steel shim.
