saw some cool small bore heads at PRI

http://www.mastmotorsports.com/black...20Heads&id=102

Mast Motorsports had on display a prototype set of their new small bore 12 degree heads with LS3 style ports and rocker geometry. The quality looked great and the flow numbers were very impressive

They sound pretty cool, are they a real product yet or are they vaporware?

I'm sure the intake runners are going to be a little on the BIG side imo, for a 346 motor. But looks to be a awesome piece though.

But if they are designed for a stock bore, wouldn't it make sense to cater to the 346 crowd?

It's got a discharge coefficient of 107cfm/sq. in....

To put that into perspective, ET's 255cc C5R heads have 104cfm/sq. in.

Seems odd.
