Leaking exhaust flange

Are your intakes and exaust level w/ a straight edge? If they are as close as you can get them, then donr use just any gasket.use a REMFLEX!!! They are the best for this!! I run them on my wifes street/ strip slant 6 car, and on my drag car.....they come w/ a new stove pipe gasket also.You will love them!! Themm them the guy w/ the drag car slant six told you about them.LOL
