coolant coming out by head gasket

i noticed today under my car that number 7 cylinder was leaking a tad of coolant where the head gasket would sit. but just on number 7. is it possible i need to re torque the heads?
or should i fear for the worst of blowing a head gasket?
I have arp head bolts not studs would this matter under high boost (16#s)

i think u should have head studs but ill let the fi pros chim in since im just building my first fi build right now but i know im going to be running them and mls gask which is preety standard anymore somepeople drill the rivets out in the gaskets and spray the different layers toghter with somekind of adhesive and then torque their studs down to like 100ftp

i would fear ur gona have to take the heads off and put new gaskets on with studs if ur pushen water that means ur also pressurerizing the hell out of ur cooling system under boost most likly not good iv seen my brother lift heads on hondas and blow coolant lines apart from high boost and not useing studs he never wants to listen

You should definitely get studs..

Headbolts are Torque to Yield bolts that when tightened past their yield point, they do nothing but stretch and lose tension..

Just fruit for thought..

I'd say yank them off just for sense of security...better safe than sorry...spending a little time now is better than spending alot of time later

If it was an MLS I could see re-torquing it, but just pull it off for safety's sake.

Retorque them, if it doesn't work then take the head off and replace the gasket. ARP head studs can be reused. They're not tq to yield.

And I've never heard a saying "fruit for thought".
