Anyone with Vortec heads and headers?
Do any of you 4x4 guys run vortec heads and headers? I'm at the stage in my build where I need to start thinking about headers. It's a 72 K20 with an HT383 and NV4500 setup. I'll be running Mass-Flo EFI and they suggested maybe doing shorty headers because it is better to have the O2 sensor in place close to the manifold in the collector so it reads all cylinders. I've always wanted to try a pair of Doug Thorley's though.
Anyway, looking to see what you run that fits. Can't go by any of the application guides now that the truck is not stock.
Any info is appreciated.
Thanks
