Anyone familiar, or used these heads?

These are the C5-R heads and use 38cc Chamber and come with 2.125 I and 1.625 E valves. The valve angle has also been revised from 15 to 11 degrees.
P/N 12480090 provides additional material for CNC porting and chamber shaping and starts at a volume of less than 30cc's.
Pace Parts for example has these heads listed at about 1200 each.
