I'm not sure how the TF270 compares to my KG ported Eddy heads but it's likely a step better.


Just to help keep everyone on the same page......
The low deck 512 build Andy posted about used 240’s, not 270’s.

The 240’s are a bit better than KG RPM heads on my bench(316@.600 vs 303@.600)
The 270’s are a pretty big jump up in flow from either(348@.600)

The test I’d find interesting would be the same low deck 512 Andy has here....... but with the 270’s in place of the 240’s
