Good afternoon to all,
All of the 441 X heads have the smallest CC intake runners. you had to be aware of the direction the 441 was cast into the head, I have not found a 041X head. I know that doesn't mean they don't exist. I have a couple of 041 heads - No X !
The 461 X head got all the notoriety because the intake runners were larger. Many people then thought that held true for all other castings with an X designation. The only way to be absolutely sure is to CC them yourself ! There is way too much hear say information out there.
Buyers - Beware !
Respectfully,
