I installed a set last winter. They seemed to be well made, but there were some problems. The header gaskets they give you are crap and do not seperate the 3&5 nor the 4&6 cylinders.Using the smallest head (3/8")stainless bolt, there was no way to get the one behind the #6 port started with cutting the flange and shortening the bolt. Then, you could only get to it with an ignition wrench and turn it about 1/8 turn at a time. Using the ignition wrench made it impossible to properly torque this, and even using the best Fel-Pro gaskets, that cylinder leaks. Keep in mind this is with new motor mounts. Driver side went in fine, but I had to hammer the pass. side like I hated it to clear the crossmember. On the plus side, there is good access to the oil filter in the stock location. Run, don't walk away from these. Knowing what I know now, I would buy Dougs, and nothing else. By the way this was on a 66 GTO.
