rocker stud to rocker clearance

I am in assembley of a 355 sbc. World motown 220 iron heads and studs for the heads. Problem is even with the studs turned down as much as possible they are close to the roller rockers contacting the top of the stud for the intakes only. Anyone have a number for clearance in that area? I am thinking .060 or better should be ok. If not I will have to pull those studs and trim them on the lathe.
thanks
Bob

Longer pushrods might help but you should double check the geometry if you do.

I did the geometry check and all was well but when I did it all the studs were not in so didn't catch the problem during fitting. I am using .100 longer pushrods and contact patch on the valve tip it correct by my observation. If I was using head bolts there would not be a problem at all.
