Well i finally bolted down the new head i bought a while back for my l16 in the green machine and this was the first time a head change didn't go so smoothly. The last head bolt i had to tourqe down decided it wanted to snap off into the block , turned out when i unbolted the head the part that had snapped off was sticking out enough i could twist it out with my fingers with no problem . first question is i had the whole head tourqed down and then took it off but i reused the same gasket minutes later when i put it back on with the new head bolt, the engine was cold and all but do you think i should have used another new head gasket and am going to regret it down the road? or will it be ok? Now that its all back together i put the offenhauser mani and weber 32/36 back on but i cant get it to start. I'm getting spark and correct timing and firing order but i noticed even when i don't touch the gas i can see tons of gass squirting in the carb when im just cranking? i think when my carb was off somone turned it upside down, could this have mangled it making the float stuck or somthing and the gas just pours straight in from the fuel pressure??????

Youre needle and seat has dirt or something in it, its filling the bowl up and its dumping out the mains since the level is abve their level, soon it will be puking out the vents.  Take the top off and clean it out or at least check to see if anything is damaged.  Turning a carb upside down wont hurt anything as long as you didnt drop it.

As far as the head gasket, its usually recomended to use a new one once its been compressed.  Was there any  tears or pieces of the gasket stuck to the head when you removed it?  If not then you may be lucky and wont have any problems.  I know for sure once an engine has run and heated up the gasket is ruined when its removed.

i for one have enough problems getting head gaskets to seal. i wouldn't risk it. there's a reason that "blowing a gasket" means losing your temper.

well i think i'm going to replace it after i get it running and see how it runs with the new head first, if it runs good i'll get a new nissan head gasket. I still don't know why it doesnt want to start the carb seems to be ok but when i start it seems to be spitting alot of air and gas out of the carb? shouldn't it be sucking in? one thing i forgot to do that i just noticed and have not done it yet is adjust the vales, i put the feeler gauge under a few of intake the lobes and i could probably fit 0.020in under there when its supposed to be like 0.008in could this affect it enough to not fire over? and the firing order would only change with i different dist. not a different head right?

Maybe you put the mount/pedastal on 180deg off so then the wires maybe are off 180
Put motor on TDC 0 deg on crank pully ,compression stroke
YOur oil pump spindal should be in the 11.28 position looking from the intake side down in the hole.
Now insert dist till it locks down. That Willl be your #1 plug wire. Now go Counter clock wise fire order 1342.
Valve you could .008 intake .010 ex

As for the carb
If you have elctric fuel pump is it set under 4pounds?
like 2.5-3 should be OK

Maybe when you took the crb off the top part did you set it down and step on it causing the float arm to get bent or the needle valves is sticking open just pouring fuel into the bowl and flooding into the barrels

as for head bolts used ones and L16s only require like 40pounds I believe.

 ...ya, right Ryan. But that's a given. Everyone knows that so it doesn't need to be said!  You might end up with an engine that doesn't start and backfires nice 'n loud to scare the neighbors.
