'68 307/327 70cc heads on a 1987 z28 5.7 liter tpi engine?

 

With enough work, they could be adapted, but why? They won't improve performance, they'll hurt performance.

 

Depends on your definition of "work".

Yes they will "bolt up".

OTOH, they'll probably cost around 40 HP on a motor that's already pretty anemic to begin with.

Above all, DO NOT trade in your nice 083s as cores for that chicken s***!!! Swap em if you must, but hold on to your good ones, so you won't be back here in about 3 days posting about "I want my old heads back but the parts store says they already had them melted down".
