Default Opinions or experience with Warhawk 15* heads?

Anyone have any experience or opinions on the World Products Warhawk 15* heads? I can get what I think is an awesome deal on them, but I couldn't find too much searching here. Is $1500 a pair a good price? I think it is. They've got 4 pairs at that price, 2 with 1.432" 125# seat springs good for .600" lift, 64cc and 72cc chambers and 2 with 1.550" 200# seat springs good for .700" lift, 64cc and 72cc chambers. Thanks for your help!

pretty sure when you change degree in heads you have to have special pistons cause the valve angle changes but i could be wrong?

I believe the stock valve angle on the LS1 is 15* as opposed to a traditional small block at 23*.

Thank you, but has anyone actually run them? I did some research and am not doing cartwheels over them either, but I think it's a pretty good price for an aftermarket casting.

The Warhawk heads come with large valves as well. They aren't optimal for a 346ci LS1 anyway.

Features:
# High-performance alternative to stock GM LS1 heads
# Available with 200cc or 220cc intake runners
# 200cc head has 2.055" intake valves, and 220cc has 2.080"
