W2 headers!

For those who ask about larger tubes.. these heads do not have the wide bolt pattern on the exhaust side. You can peen an 1 3/4" tube to clear the exhaust bolts (studs in my case), but the tubes are actually bigger than the port, hence, the 'step header'. It comes off the head with 1 5/8" tubes, (the actual size of the port), then steps up to 1 7/8". This enhances flow AND allows one fairly easy access to the header bolts. Plus the TTI's don't go under the tie rods, which gives more ground clearance.
