Is this a normal groove or line in a stock manifold? Figured it is probably just a manufacturing line but want to make sure.



Thanks

 

I've never seen that mark on a stock manifold.
It should be just a casting mark, but it it goes all the way thru to the outerside than it's a crack but I highly doubt that.

just port it and it will go away =-p

I wouldnt worry about it

 

It does not go through to the outside. I know its not crack, just curious if anyone else has seen it.
