I`m running rpm`s home ported by me and I`ve used em from day one w/these heads and that`s 5+ years. Good stuff.....no experience w/t&d stuff although I`ve heard great things.

What kind of spring pressures and RPM do you intend to run? I have both brands on different motors, two sets of Harland Sharps on Eddy RPM heads and one set of single shaft T&Ds on a set of Indy SR heads. Caution, the HS ratio are not as advertised, my 1.6 ratio check out at the retainers to be 1.64 and the 1.5 HS check out to be 1.54. My T&Ds on the SR heads where suppose to be 1.65 ratio and they are close, not dead nuts on all sixteen but close
