Anyone Using Copper Head Gaskets (Cometic)?

[Dibbons]

I want the best and am considering these for my small block (I wonder if they are reusable):

Why. There are composite gaskets that will out last the motor. Copper is not a out of the box install. The block and head surfaces need the correct finish for the copper to seal right. Plus there are other things each application may need for correct sealing. Myself I would not use them on a street motor. I have run them on race motors along with o-ringed cylinders.

Normal street motor Fel-Pros will work fine. I've run the under 12 psi of boost. Cometics are even better if the compression is high or more boost. They do require a very smooth deck and head finish. Copper can be tricky to seal water.
