340 exhaust manifolds on a 318 head?
« on: May 24, 2017 - 10:06:09 am »
Will 340 exhaust manifolds work on 318 heads?
I want to update to a 340 later in my build (or stroke the 318)  but I would like to install a new set of TTI exhaust pipes now but I don't know if the manifolds would work on the 318 heads until I figure out the engine combo I want to use.

That's what I have on my 318 heads and 2 1/2 inch TTI exhaust.
