Hi,

there is a protocol for heat fixation in the "Roberts " methods book 
("Drosophila: a practical approach") in the chapter "looking at 
embryos".
just briefly : you essentially collect embryos in a small steel mesh, 
throw them in boiling 0.1 % NaCl, 0.1% Triton-X 100 for 40 sec (in a 
scintillation vial), add more cold solution, and chill them on ice, 
before you devitellinize them in heptane/methanol as usual.  It 
seems to work well for certain proteins.

good luck,
Stefan
