Z44s should be OK.

I think the guy said he took out P50n06's out of it when he just called 5 mins ago.

Would the FQP50n06's work?? or should i stick to the Z44's?

The FQP50n06 should work. The originals were possibly MTP50N06Es.

The service manuals even shows IRFZ44 as the original ones, with the 100Ohm resistors.
