Default MOS-FET`s wire linked ?

can i wire link some mos-fet`s ? i`ve heard that mos-fet`s can oscilate if they are wire linked !!

the amp is a Holton symetrical 400W with IRFP240/9240 .

how long should the wires be ?

Any reasons why you have to wire linked them in the first place? They are all on board, nice and easy!
