I am going with a later 200-250 head for the hardened valve seats and bigger ports and valves. What years?
I have always thought that 1977 was the beginning of the bigger ports and such. Am I right?
Sorry for the newbie style question but I used the search function and kept coming up with about 400 hits that were anything but what I needed. I read the sticky about the head conversion but no mention was made as to the years these heads were available.
