hi
now i did for some reason think that amc make the oval heads as well! i might be wron im getting on dont ya know .

with the sqr port heads i think theres more meat in the port wall this was done to stop problems here as well.

i wonder what leads lee to that conclusion as well?

the x-section is definately bigger if you chop the end bits of an oval port exhausts they fit a sqr port head the width and length of the oval is the same as sqr port heads but sqr is sqr there is more area in a sqr than an oval with a proper gasket as well you can open them up easier as well.
