Fat head intake manifolds

Hi do all head head inltakes interchange
Eg fat head 5, 6, 8
Standard deck
Thanks Wayne talbot.

 

If you use 8 heads the intake port is longer so it raises the manifold up slightly, you need to get the spacer plates that bolt to the bottom of the manifold where the end gasket seals go to use them. Other than that you can use the same manifold for all of the fat heads.

 

Fat head manifolds

Does the fat head manifold fit both short and standard deck
Or it there two different manifolds.

 

There not the same.

 

With Brads stuff there are three manifolds short deck, standard and .100 tall. The heads stay the same manifolds and blocks are paired.
