Rebuilt 302 casting heads available through Rockauto

I could not find it either. I'm cool with you throwing the BS flag. Having run J heads with a 71 340 TQ on a 273, I'm curious and not ready to throw my own flag yet. I always look for the vested interest. I thought it was interesting in the other article that they thought Shady Dells flow numbers were a little "Happy" when they ran their own flow numbers. BS usually makes itself known in time if you know what to look for and keep sniffing.
I found it interesting that the article was titled The ******** and they stated they were building a 273 with the hope of some forced induction. All of a sudden there were big numbers, no info about the pressure cooker used, or actual dyno sheets. That's why I called BS. LOL
