Wow, thats a good break down. and of course im ridin around with my 82, (BOO!) how would i go about getting a 76-78 head? i've checked the local junkyards and either they've all been grabbed or there just arn't any. i've even searched the net a bit, when no one's looking at work, and i can't seem to find one.
