the exhaust and intake studs are smaller on the B series.
will they interchange? i do beleive so cause i "think" i have done this in the past.
sorry i can't be more specific...
cheers
 
Thanks Wayne, your right about the studs, I checked with a 3B manifold.

If it fits the 3B I see not problem, the studs could be removed redrilled and tapped for larger or maybe they make a step stud??

What is the difference between the B and 3B? Does the B have smaller/bigger valves? Port sizes?


Not a 100percent but I think the heads are identical short of the studs.
