Is the TPIS ZZ-9 cam to big for a 305??
I am looking into this cam for my 305. I have a full MSD ignition system, 3in Flowmaster catback, (TPIS Big Mouth base, Slp runners, Ported plenum, Those pieces have all been extrude honed.) 
L98 aluminum heads, and a Slp cold air kit.
I looked at the specs on the cam and I not sure if those lift numbers are with 1.5 rockers or with the 1.6's. I would really like to use a set of those 1.6 Crane Gold Race rollers with my new cam, or would I have to stay with the 1.5's

Stay with 1.5 ratios.
As far as clearance problems , you wont have any going to the ZZ9.
Since you have a lot of mods I say go for it.(the heads being the most significant) I had bought a ZZ9 cam but later sold it because I wanted to keep my intake manifold and heads stock.
