Default Guys running GM MLS ENTER HERE

I asked this in here because most of you guys run this gasket so.....I have searched and cant figure out which part # I need. I need the GM MLS gasket for a 3.905" bore. Also how thick is this gasket?

thanks

dont think they make it with the 3.905 bore (GM anyways).
most use the over sized 4.0" bore.

you can get a cometic 3.905 bore, they also have several thicknesses to choose from.
