General Tech Tripple Weber Swan Neck Manifolds for Triumph?

[Hurricane]

Hi,

Picked up these six cylinder manifolds described as for a Healey but I don't think they are, as the top two head stud holes holes are blind, thus bolting to a Healey head is impossible. I have been told that Triumph used a clamping method located via dowel pins which would make sence with these, but not sure, or if they did, or which models adopted it. Any ideas chaps?

Cheers

Looks like you might just have a set of manifolds for a GT6. I know that they offset the carbs down a bit on the GT6 for bonnet clearance when you could readily obtain Weber DCOE kits for the GT6. I've seen non-offset manifolds used for a triple DCOE set up on a GT6 and to clear the Webers they cut out some sheet metal from the bonnet and fabricated an elongated blister that was then faired into the bonnet.
