I don't know how to link it. I am a TOTAL computer idiot. Just go to chevelles.com and look in the engine forum for a thread "8.1 heads" .
That site is set up pretty much like this one. You will have to join to post questions.
So far everyone over there has been really nice, in spite if the fact that I don't own a Chevelle. I had my engine build plan posted there. In fact the guy who is supplying the rotating assembly is on that site (Mike Lewis Racing Engines). He has done motors for guys on this site as well. It was another member here (gmorris) that referred me to the Chevelle site and Mike.
Good luck with it and be sure to keep it all posted.
