041 X heads

[outlaw]

The old timer that told me that info also said they were bigger in the bowl area so he was right about that part. Was thinking that maybe back in the day when gm ran a line of fleet vehicles maybe police and taxi were the same.

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,
Henry Kunz 1534 H/SA

I’m doing ok Billy, thanks for asking !

Some days better than others. Looking forward to spring and being at a track even if it’s just to schmooze with all my friends.
