Cometics head gasket question

[stickybones]

Anyone ever pull apart a cometics head gasket and just run the two outer skins back-to-back for a 0.020" steel shim style gasket?

why would you want to do that anyway ?

Because I want a 0.020" thick gasket. I've since found out that Nick Micale still has some of the old discontinued hot air steel shim gaskets that are ~ this thickness.

I just thought it might be an option for anyone who used to or wants to run a thin steel shim head gasket and can't get them because GM discontinued P/N 25524599.

I see you running alky , NOT 100% sure but you may not be able to run that 24 -26 PSI boost with alky and HG as thin as 0.020 " ,which would defeat the purpose ,hope somebody else will join in on this issue ?
