intake leaking
 
i just noticed the drivers front of the intake leaking antifreeze.I installed a new Edlebrock air gap with new gaskets,torqued the bolts to the proper sequence and it leaks.aside from the gaskets,would you guys replace the intake as well to be on the safe side? [509 merlin3 with iron heads] it is avery small amount of antifreeze.thanks for the help

Could it be leaking from the front couple bolts, or any water plugs you have. Those all could use some sealant or thread tape.

Did you use a front and rear gasket, or a bead of sealant around there. I've had much better luck with the sealant, rather than the gaskets. Could it be that your block or heads were shaved a little?

the motor was running fine,no leaks when it was taken out before i bought it.i did not use the front and rear gaskets i used sealant but it is not leaking there it is leaking on drivers side top front edge were it meets the head about 3 inches back from the front of motor.

I would say either warped flange on the intake or warped surface on the head. Take a straight edge and check.

Keep an eye on your oil to make sure its not leaking into the intake valley also..
