I just got my head on my 44 put back on and noticed a little seep on the manifold side. I havnt even preasured the system yet, any advice. I torqued them to spec's and correct order... I hope
 
I'd give her a treatment of irontite, unless it's puking out a large amount of coolant. My dad's 270 Leyland had leaky liner seals 2 years ago, it was going to be her demise otherwise. It still hasn't put any coolant in the oil.
 
After you warmed it up did you retorque the head like you should or did you skip that all important step
 
When ever I replace head gasket on any thing from lawn mower to big engines I have the head planed, it will seal better and eliminate greef down the road later
 
there still is another step.
start it up and get it warmed up to operating temp for an hr. and retorque and reset valves.
a lot of gaskets have the sealant built right in the gasket and seals when up to operating temp.
also have the threads clean and lubed with neverseize or coppercoat . going 5 percent over spec is ok too.
 
It was a felpro, and I did retorque. Head was planned, block thoroughly cleaned, no new studs is that where I went wrong. Doesnt leak alot just enough to irritate me. Little seep
 
Since you had the block planed, you had removed the studs to do so. Chances are you are getting seepage past one of the studs in the block (threads). This seems to me to be a common leak point, if on the manifold side (near the front, right?)...

You could spin that stud out, apply sealant, then spin it back in, and torque the nut.
