I have some extra .075 silicone with fiberglass seal laying around from the leftovers from the aircraft valve cover gaskets I mfg
I sent a AAZ intake to extrude a hone for polishing and I wont use silicone gasket material for the intake neck
I will send the neck to the steel rule die maker and click out some of these seals
let me know if anybody else wants some and I will get some in the mail to you
here is the material shown
