E-street vs Promaxx vs 440 Source

This is the very story I was thinking of when I suggested you're likely not a machine shop customer for the heads...
well, I understand it happens to the best of them. I went to school with that guys son. His son had a Z28, and we raced (I had a 318 Demon). After I beat him, he looked under my hood hoping to find the "hidden secret" ... LOL. He went home and discussed with his Dad, who did the machining for my friend who had the Mirada that ran 9.20's @ 150 mph. The guy was a racer and machinist and he could build, but just like PHR stated, everyone can make mistakes and every head needs checked. "Wouldn't it be grand to go back to the 80's.... where rioting in streets happened in Lebanon and Covid meant what ?"
