wont start

i have a 75 mercury comet. it has a 351 with a c4 tranny. car ran good but oeverheated so i replaced the head gaskets. put the car all back togather and now it wont start. i have gas fire and air but she wont turn. i even tried starting fluid. the timing is still on, i never messed with the destributor. i just cant figure it out. the coil has spark the plugs are getiing the spark, but it just wont start. it turns over acting like there is no spark but ive tested all the plugs and the coil and they are all getting spark. im just confused... it ran the day i tore it down. now just wont refire. the plugs are new and the wires are still new. the coil is not very old. any help will be greatly appreciated.

can you see gas shooting out the jets?
have you verified compression?

After that:
reset TDC and re stab the distributer.
check float heights
check firing order / plug wires
