industrial head casting numbers
Posted: Mon Dec 20, 2004 7:43 pm
Hello all, I just picked up a new toy:
It's a 600 amp hobart welder, powered by a 56A industrial hemi. It is going to need a bit of work before i can fire it up, which i am working on now. I have a question about the heads. I pulled a valve cover off yesterday, to check the head casting numbers. The number on the head was 1677441-1, which i can't find on any casting number lists i've found. They look like passenger car heads, with the smaller valve stems, no rotators, and no extra accessory pads on the front. Does anyone know what the deal is with these heads? Mainly, my plan is to pull the hemi off the welder, and use it in one of my model A's. The motor is supposed to run good, with few hours on it, and it does look the part, but I may pull the heads and inspect everything before i use it, and maybe go through the heads depending on how they look. My real question is, are these heads good for perfomance use, how big are the ports, and how big are the valves? Thanks, David
