from what I just read on the corral the new ones have some more meat in the runners, either set are good though..

More meat meaning theyre smaller? Im going to go look Friday on the way to the LA Auto Show, so Ill know more then, unless the guy remembers something and emails me(which is what I told him to do). We will see.

by "more meat" i think that would be better cause you'd be able to port them more.

like I said either version is good, I know someone that was using an older casting on a 1400 horse car, myself and some other people I know are using the new cast on our cars

The hi port is what started it all. When your serious you use a hi port. The new version do have more material in the port. They are typically 64cc out of the box and 192cc intake port. The exhaut port is raised .750, I use them on alot of engines I build, and I use them on my own junk as seen here http://347strokers.com/category/cylinder-heads/
