* Zloty underperforms, crown jumps on cross unwinds
* Forint extend post-election rally to near 4-wk high
WARSAW, April 14 (Reuters) - The Czech crown rose to a seven-month high on Wednesday as emerging Europe's currencies firmed, but Poland's zloty underperformed with the risk of the central bank intervention hovering.
The Polish central bank surprised markets last Friday with its first intervention since introducing a free float in 2000 as it aimed to temper the surging currency's impact on exports and the overall economy.
Some analysts have said markets may again test the bank's policy.
"The zloty should be stronger today, looking at the level of the euro against the dollar, but a risk of intervention halts its appreciation," said Jakub Wiraszka, dealer at BRE bank in Warsaw.
Polish markets have held up following the Saturday crash of a government plane that killed President Lech Kaczynski, central bank governor Slawomir Skrzypek and other senior officials.
But the zloty's appreciation pace -- which has already added 6 percent in value to the Polish unit against the euro this year -- has come to a halt following the weekend events and last week's interventions.
The crown was propelled to its highest since September this week partly on squaring of long zloty positions against the Czech unit.
By 0724 GMT the zloty <EURPLN=> was a touch up against the euro, trading at 3.868 and the crown <EURCZK=> had risen 0.2 percent to 25.06 per euro, bringing its 2010 gains to 5 percent.
"There could be some profit-taking on the zloty/crown trade; it looks like some people are squaring long positions on the Polish zloty," a Prague dealer said.
"So the crown can test the 25 (per euro level)... and could go slightly below."
Markets have watched cautiously the Polish central bank following the governor's death.
The bank's acting governor Piotr Wiesiolek told daily Gazeta Wyborcza on Wednesday the country should name the new head of its central bank without unnecessary delays. [

In other trade, Romania's leu <EURRON=> and Hungary's forint <EURHUF=> were each up 0.2 percent, with the latter at an almost four-week high.
Central Europe's improving economic outlook has driven the region's assets to multi-month highs this year. Hungarian markets have also rallied this week following the sweeping victory of centre-right Fidesz party in Sunday's first round of parliamentary elections.
"The present sentiment points towards further forint gains, and a commitment by the next government to reforms can further boost confidence," analysts at Raiffeisen wrote in a note.
"However, we believe the forint's gains could be limited as it approaches 260, as excessive forint strengthening does not serve the interests of the economy."
