[R] Factanal loadings as large as 1.2 with promax -- how unusual?

I am performing a large (105 variable) factor analysis with factanal, specifying promax rotation. I kow that some loadings over 1.0 are not unsual with that rotation, but I have some as large as 1.2, which seems extreme. I am skirting the assumptions of the model by using responses on a 7-point rating scale as data; I may have to go back and compute polychoric correlations instead of product moment, but before doing that I would like to know if others have had equally large factor loadings using data that are truly interval level data on continuous scales.  

Thanks for suggestions or information,
