www.mortec.com is one of may sites that have a list of head casting #'s and some info on what they came on.
Those "083" castings have good street performance potential
if you can/will spend the time modifying them.

Probably not a good Idea to **** people off and then ask them for help.........Now if a guy was to apoligize for being a total ***** head, then acted like a gentleman....Id be willing to forgive and forget...but thats just me...looks like you have stepped on a lot of toes here...
