So any model HIF6 will work if you just get the linkages sorted out?

I'd have to see them to be sure, Rhys would be the guy who knows that for sure.

Are those parts easy to come by?

I wouldn't know where to get such bits from in North America, I generally make my own linkages from whatever is available.

I have the all-in-one intake/exhaust manifold with the secondary butterflies pulled and holes plugged. Did the HIF6 work on that intake.

Absolutely. Just some Stromberg heat shields will do, but I would use the HS6 shield if you have it + phenolic spacers + Stromberg shields. Performance wise there isn't anything wrong with it other than it is heavy, I've often wondered if some extra MPG could be gained with the butterflies working properly.

My preferred twin SU manifold for performance is the non-US market one piece iron manifold, I think Volvo made the balance tube much bigger than the aluminium manifold for a good reason + the dual downpipe exhaust manifold is as good as any tubular header when you are limited to SU's. The only time that the aluminium manifold becomes useful is when you manage to find a couple of 2" SU's.
