I am thinking flow numbers off the top of my head. I'm sure the cnc Speedmasters wouldn't come close to the TF's and the cnc TF's probably flow less than a untouched W2. I don't know the numbers. Just guessing.
TrickFlows max out around 300. My stock W2 head’s years ago stock flowed [email protected] then fell on their face. With a little port work and the stock 3/8 (2.02 valve) they easily went over 300. I’m sure with a 2.08 (11/32 valve) they could push the 330 cfm area and probably more really leaning on them. Such a beautiful shot side.
