PHILADELPHIA (AP) _ For 170 Soviet men and women and 169 Americans, the first U.S.-U.S.S.R. Emerging Leaders Summit ending today was a week of intense discussions they'll long remember as they head for home or sightseeing.

A few delegates, including conference leaders, plan to head for New York Thursday to meet Soviet leader Mikhail Gorbachev.

They plan to give Gorbachev their ''Final Appeal,'' a report on the meeting scheduled to be released at this morning's closing plenary session.

On Friday, the Soviet delegation and many Americans will attend a reception at the Soviet Embassy in Washington.

The summit was sponsored by the Columbus, Ind.-based American Center for International and the Soviet Committee of Youth Organizations. A followup summit is planned next year in Moscow.

At the summit's start Thursday, U.S. Sen. Arlen Specter, R-Pa., urged delegates to speak out on the issues that divide the two world powers.

The Soviets and Americans talked frankly, taking their cue from the Gorbachev policy of ''glasnost'' or openness, on 16 topics including international business and trade, the mass media, youth work and social services, religion, education, urban development, global environment, international finance, and science and technology.

Soviets also ventured out into the streets, to schools, to law offices, to television stations, to a road construction site, even to a so-called citadel of capitalism - the Philadelphia Stock Exchange - to see what Americans were doing, and how they lived and worked.

Inna Novikova, a Soviet interpreter, spent some of her time interviewing homeless people she had seen while being bused through downtown Philadelphia on the way to dances, concerts, the Army-Navy football game and America's historic Liberty Bell.

''Not everything is perfect in this country,'' she said after visiting some of the poor. ''There's not as much wealth (in the Soviet Union) but we don't have the tremendous poverty either.''

It was different for some delegates at the nation's oldest stock exchange, where they swapped Russian rubles for American dollars, strictly for souvenirs.

Rein Kaareprere, assistant to the prime minister of Estonia, one of the 15 republics that make up the Soviet Union, said he expected his country may soon set up a stock exchange.

The Soviets also hope their ruble soon will be accepted as currency in international trade. Currently, they must buy foreign goods with hard currency that can be spent in the West.

''It is a barrier to trade and has to be destroyed,'' said Vladimir Ogorodnikov, deputy director of a Soviet watch factory, as he watched stock traders shout.
