Just to be perfectly clear mine is the older intake style with "3800" stamped in the top of it.
Take a look at my "L27 under LN3" thread. The pictures show the differences between the heads. You'd either need to put the VIN L heads on your VIN C block, or get your heads machined for the PCV ports.
FWIW, I'll have a complete VIN L (L27) intake system available shortly. The differences in the fuel rail connection, and lack of EGR, were the main reasons I decided to keep my current induction system. I hope to know in a few days whether or not it runs any better; if it does, it'* the cam, not the intake.
