Re: 427 head questions...
Our COPO Chevelle was shipped from Baltimore in late July. It has the 840 heads. However, the engine was built in early April. Obviously the heads were cast even earlier. Just because the car was built late in the year doesn't necessarily mean that you have a late year engine. It is my understanding the 291 heads were built with both large and small plugs. What heads did the late year L78 Camaros use? Were they large plug 291s? Correct me if I am wrong.
