well, i screwed the pooch on this one.
long story short: while re-attaching the HE's to the heads, i stripped 3 exhaust studs at the head. i swear i didn't even put 12lbs of torque on the little bastards, maybe they were just tired. in any case, i've got an exhaust leak at the head (1 and 3), which leaves me with a little project. and,
i don't know how to drill and tap the heads. has anyone done this? would someone be so kind as to guide me through the process? what studs are needed, etc.? my hand drill is charged and awaiting your instructions.... thanks

p.s. i used new copper exhaust gaskets, and took care that they were properly seated in the exhaust ports, so i don't think that's problem. the car is a '75 with the (shitty) late-style exhaust. if anyone has a header for sale, i'm interested.
