Ok, now that you showed me the water jackets under the intake I'm convinced. That is just superb.
I'm thinking of the 155 head on the 75 TS block, that would fit I'm hoping, can't see why not?
75 TS head on old nord block is more difficult since the head studs are different length.
I did mean the relief for the injectors, there are none on the 75 TS head.
On that side shot of the engine with manifolds, is that the water pump on the front cover where the PS pump is located on the 75? Looks nice and small...
I got a dissassembled 75 TS in my garage, I'll try to snap some pics asap and post them here. big difference in the mating surface of the intake/head.
J. Steck doesn't like to bore down into head so he has stud nuts that are longer and stepped similar to a wheel lug nut so you only enlarge diameter of hole not bore down into head to recess the nuts and they still clamp from above. Also he recommended not trying to replace the studs with longer ones, also more expensive than the nuts as I recall.
Yes, that's the water pump (but its on the wrong side?but I'm not sure about that, it may be fine still some more research) as the water exits the rear of the head where the thermostat bolts on (shown in the CD diagrams) where it would interfere with firewall of GTV and spider etc..and runs forward to the radiator on the exhaust side, the opposite of the TS75 and Nord motors another difficulty in using the the 155 engine in an older Alfa.
I suspect that the relief is not needed in the head of a TS 75 because they are farther away from head in that perpendicular manifold runner, they really optimised the 155 head with the steeper runner angle and injector closer to valve, truly SWEET!!!!!
