.080 Base Spacer,  gasket or not?

[69ls1]

I am getting ready to put my new engine together. I used the JE turbo pistons with an .080 aluminum base spacer. What are you guys using with the spacer? Do you run 2 base spacer gaskets, which will lower compression even more, or are you guys just using a sealant on the spacer?

Just Copper Kote both sides.

Copper coat on the spacer.

Check your clearances and quench area and then decide.

ran mtc tall deck stock bore with a .060 spacer and copper coated both sides

So what do you guys mean by copper coat? Is that like HI Temp copper permatex or something else? What brand?

Thanks.

[JIMMY]

spray copper sealant, maybe made by permatex, but not 100% sure, i have 3 cans of it, you think i should know the name, but you can buy it at any local part store

[rocketgeezer]

Yes it is made by permatex 2 or 3 coats on each side should do the trick

Thanks.

I used the spray copper today for the first time. It works very well. Thanks again for the info.

So no headgasket needed?? Im confused

[69ls1]

You still use a Cometic head gasket. You do not need to run a base gasket on the bottom of the cylinders, that is where your .080 spacer goes. You just use the copper coat on both sides of the spacer and head gasket. 2-3 thin coats.

i ran a base gasket on mine when i had the spacer
so it was basically a .09 spacer
but either way will be fine
as long as the pistons are in the hole enough

my next build im gonna attempt to run shorter rods vs the spacer
to see how it works out
