Which are the casting numbers on the inline 6 head that are the highest flowing, I think they are the 7120, I am not sure though, input and corrections gladly accepted. Thanks for your post!!!

From 1991-95 (Ive Seen 1990's) on some heads the casting read 7120 For performance this would be the best head to get a hold of. I read somewhere that these heads have the highest intake and exhaust port airflow and work best when you have lower valve lifts.

i have 3 of these heads at my house but i have another question, they are all different one of the heads has a casting that says NH2 and the other two have the Casting NH4 what is the difference? Does anybody know?
