Narrative:

Began flight knowing that weather would be VFR with various cloud formations 3000+ ft. Requested and accepted clearance through jfk class B; climb to 5500 ft. Encountered cloud buildups and climbed to 6500 ft; and then 8500 ft. Encountered cloud tops above that altitude while radio was *very* busy. Elected to poke through those cloud tops rather than deviate from assigned altitude or heading. Being an IFR pilot on a VFR flight plan; I judged that a short period of IMC would be safer than deviating from my assigned course in a very busy piece of airspace. Completed flight uneventfully. Next time; I'd opt to travel around rather than through this airspace if weather made it impossible to be sure of being able to complete the mission in VMC.
