WATER IN HEADERS PROBLEM?

Hello, I have a new 604 cid in a fox mustang, the motor is new only a few runs in the dyno day, my heads are trick flow fully ported and cometic gasket, the torque was 180 lbs.
The problem is after a few runs in the track began to come out a litlle water by two headers in the passenger side so I checked my oil and also has a litlle of water. What is the problem? What can i do? Any information is welcome.
THANKS

Blown head gasket, cracked head

If you're not living on the edge you're taking up too much space!

take the headers off, pull the plugs, then presser test the cooling system, this way you can find the cly (s) which are leaking and go from there

The cylinder are leaking are 1 and 2. The Heads and gasket looks like OK.
Do you think is recomedable to mix a little of block seal to see what happens?

If you've got two cylinders side by side that are leaking coolant then the head gasket won't be sealing. If the gasket looks good, maybe the head's warped. Or maybe a few head bolts didn't get tightened.

Would 180 ft.lbs. of torque be over torqued?

Later Mark.

The motor was assembled with 180 ft lbs of torque w/oil I dont think they was wrong with this torque and this type of gasket but I am going to check both things.
Thanks

leaking continue

Well, I retorqued the heads, all bolts are 180 lbs and mix a block sealant in the coolant so I start the motor for a few minutes and the motor began to increase the pressure in cooling system until the radiator leaking coolant in the cap. So I am going to pull out the motor and head locking for blown gasket, porting damage, head wraped or craked or anything else. I hope the heads are in good condition.

Water where it shouldn't be....

One thing to check is the surface finish on the block deck and head. The Cometic gaskets require a very smooth surface. A finish that works well with a Felpro...will leak bad with a Cometic. If the surfaces have a "tooth" that you can feel wit ha finger nail...it may be too rough. I went through this problem on my 605 and ended up decking the block...with a much smoother finish.
I really think that the 180 is too much. I have a very similar deal...and I think that I used 140...or 145.
I hope this helps.

Thanks for reply, today morning I pulled the motor and heads, the sleeves, jackets, heads and gasket looks like OK. I was checking the finish in the block and is not a mirror or very smooth surface, maybe this was the problem.
Regarding the 180 lbs torque is because is a nitrous motor, it has 3 shoots 250 foggers+250 foggers+175 plate, this was the reason for a cometic gasket.
I need to take a desicion, if a put a Fel Pro on it Išll not use nitrous maybe one shoot and I will use my N/A 4800-5000 stall. The second option is to prepar my block surface to try again with Cometic gaskets and a nitrous converter 3500 stall. The motor made 1031 hp N/A.
What do you suggest me?
Can I use a felpro 1028 with bore 4.67 but my bore is 4.625?
SALUDOS
