[QUOTE="Thombar, post: 223070, member: 5870"] Could not find a machine shop that could service these heads. Ive cleaned and mildly re-surfaced myself to be sure warping hadnt caused the coolant leak. I cleaned w/ kero and scotch brite then wd40 and razor. Used a 1' piece of glass, to be perfectly flat, blacked surface w/ marker, 220 then 400 grit w/ no downward pressure. Only took 10-12 passes to evenly remove all black, 5-6 more w/ 400 to finish. There are what appear to be casting imperfections in both heads. I didnt try to remove, not depressions. Will fit right head and compare compression w/ good rear cylinder tomorrow. [/QUOTE]
