I have a pair of C4AE 6090G big port heads for sale. These heads are listed among the most desirable oem cast iron heads. They are complete assembled w/ original valves and springs, no rocker assy's. Good used condition, no sunk valves. $400.00 plus shipping. I can also rebuild these heads, and would be willing to do some light port/bowl/chamber (cc) work as well, for an added cost, of course.
Thanks for your interest.
