You can get a good cam and lifter set from Summit or Jegs for ~$100 that will pass smog all year long and give you more power. Dont limit yourself to stock stuff.

From the tech data on this board:
https://www.thirdgen.org/tech-data
I'm guessing the L69 cam is
305 AT 14088843 .403 .415 202 206 114.5 (115/-114)
And the LG4 cam is
305 AT 14094097 .350 .385 178 194 109.0 (106/-112)

FYI, I'm using a Crane Compucam pn 114122. Its a very mild cam but a step above stock in my 84 z28 L69 and has no problems passing emisions here in NY. Of course CA is a land of its own rules and regs ! I also have a very low miles used L69 factory cam if you need it. With new lifters it will work just fine.
