Life after headers....
I ordered a set of American Racing headers with cats for my 94 and wondered what my next step should be for a little more performance. Ported air intake? Roller rockers and springs? All i have done to it so far is new plugs and wires and i added an SLP tri filter air filter system and had it tuned by lt1pcmtuning. Any suggestions would be highly appreciated!

You will notice a stall.I would recommend doing a shift improver kit(use stage one-or first stage of improvement for a street car)and an auxillary trans cooler to ward off heat.
Roller rockers and springs will give a few ponies on the top end.
Really no need for intake porting or a larger throttle body.
Replacing the stock resonator with an x-pipe will give it a few ponies and a cool sound.
Make sure your tune is spot on after any mods.
Depending on what gear you have a change to 3.45/3.54 will wake it up and also allow you to pass fewer gas pumps.
Past these you have to jump to a cam and/or heads for noticeable power.This would be the time to do springs and 1.6 rockers IMO.
An electric water pump is worth a .10 at the strip but I would save it for after a cam install when it is removed if done at all.

Car is at a local shop right now getting a complete Stainless Works install.
Long tube headers (Jet Hot coated), cat delete, x-pipe, and chambered mufflers.
Mine is also an automatic.
Motor is otherwise stock and a cruiser, not a racer.
But of course, I think we'd all like a little more performance.
I have the build sheet from the National Corvette Museum that contains all the codes.
There is a line item that states, *GM1 2.59 RATIO AX so my guess is those are my rear gears.
Can anyone confirm?
Thinking a cam swap might be down the road as well... Something a bit lumpier maybe.
scottermis, I will be interested to hear how you (and others) wake up a stock LT1.

I also went with a Vigilante.
The right cam would also make a noticeable difference.
