Re: I've got a really stupid question....
Nope, can't tell you definitively that you can't because you didn't say what motor your fancy cams and heads come out of!
I'm assuming they come out of the Alfasud Ti in your signature, which presumably has the original motor with solid lifters in. As far as I know it's possible to use the 1712 heads (bigger valves? recessed combustion chambers?) with the non-hydraulic lifters and camshafts. But I think the smaller capacity motors didn't have a recessed combustion chamber in the head, or something, so if you put those heads on your 1712 block the compression ratio will be too high?
When my last motor died I tried to investigate the 1712-head-and-solid-lifters setup, but how to achieve it seems to be a closely guarded secret among those who race boxer Alfas. They all wanted to tell me it was very difficult and they didn't know how it was done. But a friend of mine took some of the parts from my dead 1712 motor and did a dummy fit with some solid lifter bits, and found a combination of parts from each motor which appeared to work.
