I have 2 sets of heads for sale, the first is a bare pair of 148 big oval ports that are good. The second is a complete pair of small oval ports (236) that have about an hour of time on them. The set of small ovals has had the chambers cleaned up on them, would like to get $150 for all 4 of them but they are in my way so I'll take pretty much anything to keep them out of the scrap bin. Located in the Lodi/Stockton area, make me an offer, Mark (209)-747-2715
