Well I guess I'll just clean up the T120 head and cylinders and put them up for sale, then pay for the proper set to go on the TR6R.
I already have more projects to work on without rigging something that I want to put my backside on and blissfully ride around the county for days on end.
The T120 engine case is damaged so it has no value, but everything in it can be sold off to help get the other one up and running.
Sounds like a plan.

Why are you trying to rebuild a '72 engine with an 8-bolt top end?8-bolt stuff is pre-'63.
Keep the 9-bolt barrel and pistons and pushrod tubes to use on the '72.Get a '72 head and rockers.

Sell the 8-bolt stuff that is now becoming rare.

I have been searching for the information you are talking about.
The 8 bolt head and cylinder came off of the 72 tiger 650 engine, JG33xxx. If that isn't the proper items for that year, then someone must have put them on years ago. The #2 engine, a parts engine I have, NG36xxx came with good set of pistons, cylinders, and 9 bolt head. If this is true then all I need to do is swap them from the parts engine onto the engine I am rebuilding, right?
I was looking for replacement items like the ones I pulled off so I can keep it as built originaly.

here's is something else to consider.
The The 8 bolt head thatI pulled off is a single carb head. It is also the one with a crack into the valve area. And the cylinders and pistons are 60 over.
The parts motor has a good 9 bolt head and has cylinders and pistons that are standerd size. but it is a two carb head. So which is correct for a 1972 Tiger 650?

How 'original' do you want it? The TR6 would originally have had only one carb but lots of folks have swapped the TR6 heads onto T120 engines and vice versa (purportedly for simplicity and performance, respectively), so it seems safe to assume you'd be fine using whatever head you've got. The cams were different, though I don't know by how much and doubt it would be much of a problem as long as you're careful with timing, carb setup, etc.

Also: are you sure it's a Bonneville head? I had the impression that the TR6 single-carb manifold would bolt right up on the T120 head, meaning the heads themselves probably look pretty close by themselves...?

Yes, they pretty much look the same except the 120 head has 9 bolts and two carbs.
The TR6 head has 8 bolts and and only one carb.
Keep in mind the above is as I pulled them off the two different engines.
I'll look for part numbers on both later today and will post my findings.

The red one looks like it has a single carb head,but no manifold.The rocker boxes won't be right for the '72 frame and you'll need OIF 650 inner head bolts.
The head may or may not fit well with the later '72 rocker box gaskets.You could always build it up with JB-Weld around the inner 3/8" bolts to get enough gasket surface for the rocker gasket.

TR6 used the same cams and timing as a T120.
