I haven't been able to find much info on these relatively new heads. But, I did find this link Head Flow Numbers (http://users.erols.com/srweiss/tablehdc.htm#Chevy) and the data shows these heads outflowing most competitive Aluminum SBC 200cc heads. Also, they're not much more expensive than the non Platinum I.E.'s. Has any body had experience with these?

Bump.

TTT

I have the I.E's lovem.
