Speedmaster heads part 2. Plus intake work
Stock exit. Detailed and exit. Being my son is probably going to be using a 1 5/8 street type header I’m forced to stay on the small size of things. From the factory these heads have a step almost the whole way around the exit point. Just taking that out really opens the exit up some. The corners are even worse. Stock and slightly modified.
