Just got them off of e-bay. They are E7's with 1.94" intake/ 1.60" exhaust valves. "Massaged" intake and exhaust ports. They had 62cc combustion chambers before resurfacing. They include bronze guides, positive stem seals, 4130 moly retainers, new valve springs...don't think that's too shabby for $400. Now I just have to get them here to hopfully have my car done by the Goodguys PPG Nationals this weekend
Not bad for freshened up heads. I picked up some GT40's with about 40,000 miles on them from $250 from a friend's dad. I'm going to clean them up a bit including some port "massaging", but I think I'll put the IRS in first.
