Bowtie Phase III vs Other Iron Heads

Does anyone know how a Bowtie Phase III would hold against a World Sportsman II? The Bowtie has a 184cc runner and the Sportsman has a 200cc runner but I know bigger doesn't mean better.
What about the flow numbers from 100-600 lift on the Bowties? I couldn't find them anywhere on the net.

This is meant to compare "out-the-box" performance between them two heads. I can buy either set for same money.

The Sportman heads flow is as follows:

Lift IN EX

.100 70 49
.200 107 95
.300 176 124
.400 210 130
.500 218 138
.600 222 142

I think you might have the flow numbers for the S/R Torque head.The last set of Sportsman's heads I did flowed over 240 at .600 out of the box with a 2.02, 1.6 valve.

This info may be helpful....

I don't know. Came from the tech at World. I asked for numbers on the Sportsman II 200cc heads. Sounded low to me also.

thanks tech, really good link.

Eric's right Camaro, your numbers are low for those WP Sportsmans, mine are the same as Eric's.
I don't know the numbers for the stage III Bowties.

Great link there Techie ! Thanks.

These numbers are messed up, the tech threw in some at like .150 .350 .550 etc. I called back to see why they gave me the wrong numbers and another tech says that's how they were listed in the computer. I would redo the numbers but that link is close enough that it would be useless to do so.
