guide to retainer clearance.
I'm buying a lunati voodoo cam and I need to know how much lift, before retainer and valve guide contact. My heads are HO 305 heads with 2187 casting number.

187 casting heads? hmm...
You can measure it. I might suggest using .050" offset locks, it's cheaper than machining, and gives you a bit more safety margin. I think that's what i've got on my 305 heads, when I had my lunati voodoo 60103.
