'AFR 185 cNC Windsor Ford Flow TestThese are the flow numbers on the Westech bench using Tom's heads that are angle milled to 51cc chambers. This is with his 2.20/1.60-inch valves and valve job on a 4.030-inch bore with a radiused entry on the intake side and no flow tube on the exhaust side.
| VALVE | INTAKE | EXHAUST | E/I |
| LIFT | | | |
| 0.050 | 32 | 24 | 75% |
| 0.100 | 67 | 56 | 84% |
| 0.200 | 145 | 114 | 79% |
| 0.300 | 202 | 155 | 77% |
| 0.400 | 230 | 174 | 76% |

| 0.600 | 265 | 185 | 70% |
| 0.700 | 272 | 188 | 69% |
E/I represents the flow relationship in percentage of the exhaust port to the intake port. Generally, percentages over 70 to 75 percent are considered good.
