Another opinion question
I use 4.00 and 4.50 bore sizes as these are the two most common around here. Without knowing what I've done you should be about 25-30 cfms less with the same size valves. The 2.02s should be in the 250 range and the 1.88s should be in the 240 -250 cfm range.
4.00 for small blocks and 4.50 for big blocks.
