OK...here goes straight from Dwayne's E-mail to me this evening:

Lift" I/E

.100 72.5/58.2
.200 153.7/118.6
.300 224.3/178.2
.400 285.2/218.2
.500 329.6/232.8
.600 361.9/245.1 (edit-read wrong column)
.650 368.1/249.9
.700 364/253.1
.750 364/254.7
.800 364/256.3

Through .600 lift they are dead on (within ~1% either way) with Chapmans website numbers published here:

It's nice to see "Real" Moparts numbers off of "Our" bench, makes me feel better about them that they've been flowed by Fast Hisself

I asked Dwayne why they apparently "stalled" at .700 especially when they were still slightly climbing from .600 to .650; On the Chapman bench they apparently peaked at 381 @.750. I'm not going to be running a cam much bigger than ~.680 but I'm still curious about that.

I have the other one and I must say, they look really nice, Kinda reminds me of a scaled up last gen SBC NASCAR head.

They seem to be....adequate

Anyway...there ya go!!
