I want to trade my 799 casting heads. I used a die grinder and opened the exhaust size up to gasket match and smoothed the intake side. they are assembled. they need to be taken apart and have all the metal shavings blown out. These are same as 243. Can send pics of port work. I am looking to bring my compression down. If you have 317's or 241's or anything else that has bowl work done to bring my compression down. Also open to offers. I also need to heads to have springs good to .650 lift with retainers. My heads have 300 original miles on them. Willing to trade or sell outright. $600 shipped or your heads + $ or your heads + springs. entertaining offers. http://i690.photobucket.com/albums/v...erk31490/6.jpg
