Ok guys here they are. The heads look beautiful. It's amazing how large the 1.94 valve looks up close, there isn't much room there for more valve. When I sent Lloyd these heads, they were brand new, never installed on a car and Lloyd confirmed this when he received them. These heads are IRON and I used the STOCK valves. Lloyd also used the stock valve job as it was brand new and he said it was good. He did back cut the valves though. Heads are milled slightly. Intake ports look small.

Intake
Lift Stock After
.100 62.9 63.9
.200 125.0 133.8
.300 169.1 190.1
.400 205.9 234.4
.500 219.0 252.9
.550 223.6 256.9
.600 229.1 257.5

Exhaust
Lift Stock After
.100 44.8 49.1
.200 90.7 108.7
.300 132.2 144.8
.400 145.8 170.3
.500 146.0 183.9
.550 145.3 187.7
.600 145.5 190.3

Look how the stock exhaust stalls at .400 and above! The back cut and port improved flow at all lifts above .100 and the exhaust keeps ramping up! Thanks Lloyd!!! Great customer service also.....
