I have a complete pair of 289 hipo heads for sale. These heads have date codes of 4C24 and 4D24. The heads are complete. I have all the rocker arms in a box along with the one spring that has been taken off one of the valves. These heads were on a good running 302 when they were removed. One shows head as C4OE and the other head is a C5OE. You could probably use the heads the way they are. If dates don't matter to you, then these heads are for you. Price on the pair of heads is $2000 plus shipping. Email gandcmurphy@rogers.com for additional pictures. Thanks.
