219 heads
So I pulled a valve cover on my 454 and found i have 3917219 heads. I have never been inside this motor, so a casting number is all i have. does anyone have any info on these heads? They have truck cast into the head so I assume they are big chamber truck heads. Is there any performance potential here or should i just find a better casting number. I need to stick with a stock casting or I would just go aluminum.
Good to have her home finally, still need to go back and give her another polish after messing with the engine stuff. Made it up to Idaho. Also a local show.
