I have a 440 I'm installing e street heads on 75cc chambers was wondering if I could use the smaller .20 shim gaskets on aluminum heads ?
Aluminum heads and steel shim gaskets ?

Edelbrock recommends the Fel-pro performance gaskets.
My machinist told me not to use steel shim on my E-Street heads because the heat / expansion are different & a steel shim can't seal during the heat cycles.

Agree, the thermal expansion rates are very different. Don’t use the steel.
Multi layer steel. I took the rivets out and coated every later with spray on copper coat. Held up fine on every engine so far. Had one MLS problem motor. X block with Batten heads no copper coat and dripped water when cold. As soon as I got heat in it the drip sealed.
We just did a 340 with Edelbrocks. used Felpro 1008's worked fine but only 10.5 compresion.
Some motors with boost and MLS My son cuts a ring under the fire ring and adds a inkinal wire . He just did a Cummins with that wire. Very common on pulling tractors

Are you talking about the 1009 gasket ? Did you spray with copper as Well?
Yes, the 1009 Fel-Pro
No copper spray, they have a tacky feel to them when you pull them out, I dont pull them out or touch them to anything until the block is prepped/cleaned & ready to go together to ensure there are no contaminants on the gasket surface
