I searched around and didnt find any answers

are there different spacings and styles of h22 exhaust flanges (where the manifold bolts to the head) ?
Or are they the same bolt pattern and port spacing\size through all the models?

 

This is probably an easy question for an h22 connoisseur

 

why would you change port spacing when it already fits the motor?

 

H22's are all the same if thats what you are asking... H23's however are different from the H22 flange.

 

H22's are all the same if thats what you are asking...

thats what im asking and thats the answer i was hoping for

thank you
