Angry leaking head studs!!!!

I've built a couple motors...changed heads on several...and always used good ol trusty silocone to seal the head bolts from the water passages...with no problems... my latest build up I used the liquid teflon and now I have several leaks...tracks down the side of the block from several studs... best guess, the ones under the valve covers are most likely leaking too...but before I tear it down... what could I have done wrong...everthing was clean...anybody have any insight before I go back to good ol silocone...

Thanks
Nasty

Teflon is not really a sealer... Its a lubricant to help with the threads on pipe or bolts to achive the proper torque or engagement... I use either Permatex "right stuff" or just permatex #2 or "aero seal" on head bolts... I would drain the block via the plugs if they can be removed...? I always put drain valves there too... Then remove and reinstall to proper torque each bolt 1 at a time... This should keep the head gasket seal intact...

Drain the block and radiator. Start with the correct torque pattern and remove one bolt at a time and reseal and retorque. Mainly you only have to do only the ones in the water jacket in the middle and all across the bottom.
I had to do it one time before.
Dont forget to change the oil.
