Header gaskets w/ stock manifolds

Is it okay to use header gaskets with stock exhaust manifolds? This is on a 318 w/ 340 manifolds. I have a set of Mr Gasket header gaskets. Should I use them or buy the stock exhaust gaskets?

Thanks,

Put them on

I have a 440 going together with stock manifolds...using a gasket

Use them

Why use gaskets at all? In many cases no gasket was used. if the mating surfaces are flat and true, you don't need one.

I never run gaskets on the head with mannys

I do make sure they are milled flat and use the copper rtv and bolt them on,let cure over night

headers..well thats another story,IMHO

I've had a few leaking gaskets on manifolds over the years (gaskets that other folks have installed) and the manifolds don't seem to seal up after removing the gasket, and they are visibly pitted from the gaskets (those 'quilted' metal gaskets, anyway).

Sometimes 80-grit on a DA saved them, sometimes not.

Try them without gaskets, and if they don't leak run 'em as-is.
