Having some brews while blending the bowls on a set of 915J’s. Its a nice day why not. I picked them up for $150.00. Figured I could do a little work to them and replace the 318 smog heads that I currently have on my 360 at some point. They seem to be in very good shape 1.88/1.60v they had brass sleeve on the exhaust side and appear to had valve seats installed at some point. Positive valve seals as well. Merry Christmas everyone!!!
