exhaust manifold flange gasket for big block

Help!
I've got these in the past and can't seem to get the parts store to locate them.
Center hole ID is 2-1/2 inch
Bolt to bolt center is 4 inch
The ones that come with the kits does not match the hole to hole dimension
Thanks,
Mark

I would suggest getting some bulk gasket material and making yerr own.

If you are talking the exhaust pipe to manifold gasket you should be able to go to a exhaust shop and get them. Bulk gasket material is not the answer as you should have a metal ring if not a complete tin gasket. Something like 'exhaust pros.'

Yeah ... I would agree if you need the metal-ring type .. but on a free-flowing exh system .. I don't think that is necessary.
