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.

actually thats not correct smokin they do.....heres an Email from Eric at HPE about the gaskets for my 383 w/ 6.0 ltr heads."We would use the GM MLS like on yours I’d do the 9227 6.0 gaskets that go with your heads."my bore is a 3.905 as well

."We would use the GM MLS like on yours I’d do the 9227 6.0 gaskets that go with your heads."
why not just call up your local dealer and tell them that
