351 Cleveland 4V open chamber heads for sale with comp cams springs. Heads redone about 450 miles ago. $500 or trade for? Also have some high port closed chambered that have a lot of work done on them. I don't know a lot about them I would sale for $450. Last I have a set of 4v closed chambered bare heads. The machine shop checked. They need to be shaved 20 to 30 thousands to slick them up. I'm asking $200 for them.
