new head thermostat housing wont fit

[Lifted04FORD]

Hey guys

i bought a new head. swapped it on my 1g. now i cant get my thermostat housing to fit onto the new head.. any ideas? i think its a 2g head maybe?? the head bolts fit fine... everything else looks good, just cant get the housing in.. ideas?

Does this new head of yours have 3 holes for the o2 housing or 4 ? If it has 3 then its a 1g head. If it has 4 than its a 2g head. I am sure that nice guy that gave you that fresh rebuilt head at such a cheap price wouldnt screw you. I am sure he lost enough money in the deal already.

Good Luck
