More bang for my buck
My 94 was running great but at 140K it looks like the head gasket is gone (it wont start now). Since I have to tear into the motor, I've decided to "freshen up" the engine. In addition to new seals I was wondering about a bigger cam and replacing the lifters. Also, what is the prevailing thinking on doing the heads? I'm new to this and I don't want to spend $$ to have a 9 sec. car but as I'm "in" already, what's the best thing to do to add a bit without doing so much I have to redo the whole drive train.

Edited for manners: Welcome to the Forum.
You don't need new roller lifters unless they failed or are damaged in some way. LT1's do not have the old style of hyd lifters but a hydr roller lifter. Since it is a roller design it isn't mated to the cam profile like the other design is. So save yourself $300 and reuse them. The Hotcam would add additional power and cost less than $200. Lingenfelter, Crane and Comp Cams all offer a couple streetable cams as well.
Have the LT1 heads professionally ported, apply a three angle valve job and cam matched valvetrain done. Stick with the CNC types for more consistant results. Or you can go the way of AFR and spend $2000 or so for a set. But, you can sell your old heads for a couple hundred to help offset the costs some.

Re: More bang for my buck (Curveit)
when i did my 383 rebuild my machine shop advised me to re-use my lifters.. (that had 134k miles on them). They did clean them in a tranny fluid solution (soak) for a few days...
