.557" purple shaft 318?

sweet as man!!!! do you know what pushrod length is for 1.6?
I'm going to use my 1.5 adjustable rockers, they're near new Speed Pro on grooved shafts, as i have the pushrods to suit, but later it would be nice to have the option to go with the 1.6's.
7.5". ball and cup. the stroker has ally heads and 11.7 comp, so it uses the cam. its not just there for the sound. 1.6 rockers makes it around .590 lift
