This is a pic of the W2 headers installed. We drilled holes to match heads ,also the header bolts are 3/8.Stainless headers have the flanges made and in stock. And to answer the O P the heads are well worth the money and effort. Ours is in car and running but the converter was cracked around the weld and leaking so we had another one built and it is due in this week. Hope to run the car soon,but it's 100 degrees in Texas and I'm too old to put up with the heat
