I’ve got a set of D0OE 351w heads I’ve been piddling with for years. Someone spent some money on these things...new thick walled guide liners, screw in studs, guide plates, and 1.94”/1.50” valves with undercut stems. Factory valve size on these is 1.84/1.54. The exhaust valve seat appears to be original. The valves look almost brand new (supposedly 8000 miles on them after rebuild, which is believable). The contact pattern between the exhaust seat and the valve is plenty wide, but is out at the very edge of the valve. Is this a problem?
The intake valves are marked 194R, right under that is G-AH. Exhausts are 2001, C-BH. Any idea who made these?
