The heads are off the car,
Now.. I need to decide to go the vortec head & intake OR
stay with continental aftermarket heads, and intake.
Please help me..
This is a street driven car with lots of commuting.. Basically its a driver.. Thanks for any advice and help.

Honestly, the SD Vortec baseplate doesn't flow earthshatteringly well.

Stay the conventional aftermarket head route.

X2. I think you will be better off with a nice set of conventional heads and doing a self porting of the stock intake.

If you had a vortec base I would do the vortec heads. Stay conventional.
