You will be in the 12's if you get traction. I ran the same combo before, but I had the windsor jr's from world castings. I put the heads on out of the box with no port work, so with the work you did on your stockers they should be close. I used the 70mm from Accufab, and a C+L 73mm and it pulled hard to the rev limiter. If you can get a deal from Mac on a 70mm I would do it, A 70mm will not hurt that much or at all.
About the chip... If you don't have any driveability problems and it is NA it is almost a waste of money to get a custom one burned. But if it starts hunting for a idle or starts running rich when ever it wants to it is well worth the money to get one burned.
With my f303 and the C+l It would run ok sometimes, but the rest of the time it would buck and search for a idle, and sometimes die. The chip fixed it and ran like it came off the showroom floor.
If you run into some money get the stage 1 kit from NOS. It woke the car up big time and I think it ran like a 12.4
See you in April,
Wade
