Crane does too, the only thing that sucked was to use their rockers, you had to buy all new studs to get rid of the stock rocker system where you bolt them down till the bolts are tight, you have to buy traditional studs so you can adjust their rockers. All in all it cost me close to $400. It did buy me some higher rpm breathing and a little better top end.
I also have had good luck using the MSD coils on these motors to make up for the lack of coil over plug like the 2nd gen vortec motors.
