235cc TFS head flow numbers
I received my 235cc TFS heads today from TEA and they are sweet. I had them milled .010 to get my compression up a bit. I tried to take pictures but they turned out bad. These are going on a 421 iron block stroker. Here are the flow numbers:
LIFT INTAKE EXHAUST
.100 67.1 57.2
.200 147.1 123.5
.300 237.0 206.5
.400 292.5 250.4
.500 331.7 269.2
.550 342.0 275.6
.600 350.2 278.3
The intake valves are 2.08" and the exhaust valves are 1.60". My cam will be small (for this size motor) as I'm going with a G5X4. Motor should be done within the next month.
