We reexamined the experimental evidences for the possible existence of thesuperconducting (SC) gap nodes in the three most suspected Fe-pnictide SCcompounds: LaFePO, BaFe$_2$(As$_{0.67}$P$_{0.33}$)$_2$, and KFe$_2$As$_2$. Weshowed that while the $T$-linear temperature dependence of the penetrationdepth $\lambda(T)$ of these three compounds indicate extremely clean nodal gapsuperconductors, the thermal conductivity data $\lim_{T,H \rightarrow 0}\kappa_S (H,T)/T$ unambiguously showed that LaFePO andBaFe$_2$(As$_{0.67}$P$_{0.33}$)$_2$ are extremely dirty, while KFe$_2$As$_2$can be clean. This apparently conflicting experimental data casts a seriousdoubt on the nodal gap possibility on LaFePO andBaFe$_2$(As$_{0.67}$P$_{0.33}$)$_2$.

Are there nodes in LaFePO, BaFe$_2$(AsP)$_2$, and KFe$_2$As$_2$ ?
