Your opinion on the Edelbrock RPM XT Heads? I saw them in GMHP mag. and saw the quote "Tested on a Z06 Corvette LS1 engine, these heads made 488 hp @ 6500 rpm and 432 ft./lbs. of torque @ 5000 rpm with just a head and cam change."
Anyone have these heads? or anyone want to shair their opinions on the heads?
Thanks!

Are these the "new" updated ones? I'm sure the 488 HP is on an engine dyno with a Lingenfelter cam. Those heads didn't look all that radical from the picture.
