Exhaust manifold gaskets

I don't need them on a 350, it that correct?

The gasket in there are warped and causing a leak. I was going to pull them out

If you don't use gaskets, they can't leak.

You will need to to have the flanges surfaced by your machinist.

Just trying to hold on long enough to get headers.

Found a set that should fit the 80's B body

I got to get rid of the stock 307 exhaust manifolds

I don't know what manifolds you're running, but be aware that the tubular manifolds used on the later 307s DO require gaskets. Also, these gaskets have different port sizes than all other Olds exhaust gaskets.

No these are the cast iron ones.

I got lucky. They changed them 1/2 way thoght the 85 model year and I got the old ones.

If I remember correctly they are 14/17's
