hey guys i got a driver side exhaust leak on my 318 magnum. i used the magnum exhaust manifolds gaskets with a 340 driver manny, should i of had used la 318 gaskets? also i read some people had to grind off a part of the block to run 340 manifolds?
 
iv'e got an 01 5.2 in my 72 dart with a 340 manifold. i don't know, maybe i'm lucky but it's never leaked in the 3 plus years it's been in there. i have heard about shaving a motor mount ear down, but i didn't have to. dave.

I had a heck of a hiss on drivers side manifold . It was tightened to the point I was afraid of snapping studs. I heard about remflex and bought a set . I torqued to specks , haven't heard anything since , its been two years.
