Roy the owner of best gasket claimed there gaskets are good to .108” for futur knowledge. He recognized the “maybe” a person could cut a relief on the piston edge and get away with .125” and naturally discouraged that. He really stands behind his products and obviously went with the side of caution on the question. They are a stand up company and for our vendors great to deal with. I know many have done the .125 on 37’s and I have driven cars done that way but have never built one that way. I am still curious if maybe a felpro gasket or even NOS has a larger firing ring. I used to stock Felpro and have nos but again given the support best gasket co gives us I have depleted everything else so nothing to compare to.
I am also interested in what you guys have used for gaskets as I too have a .080 engine I wish to do to .125” sonic testing showed me it could easily handle it
