well, anyone that follows the hemi posts on here are most likely aware that torkrules is the latest victim of the seat falling out of a mp aluminum hemi head. my hope goes out to john that his luck on his project will change for the better! my ? then is being that john is not the 1st on here to have this happen, is there anyone who has put 10,000 miles on there aluminum headed hemi and not had problems? i'm wondering out loud if we are all going to experience this or did some good 1's get out the door and how can you tell what you have, good or bad. thanks dave
