my heads on my '65 327 have a 3755549 casting number which as far as i can find is from a mid to late 50's 283. the funny thing is "X58" is CAST into the OUTSIDE of the heads between the exhaust ports. i have no idea what that means, nor can i find pics of other heads with the same markings. if anyone knows anything, i would greatly appreciate the info.

Thanks
