As SD says, use 67's only, work perfect.

Have helped install the '67 HO manifolds on two '65's.....fit like a glove and no exhaust leaks years and years later. A great improvement. Both cars were 4 speeds.

Just make sure you get all the correct parts for a 67 HO car to route the battery cable underneath the manifolds. Battery cable, heat shield, etc.

No, the HO manifolds require different down pipes and matching flanges.
