I've heard that the equal lenght shorties arent really worth the hassel and money over the unequal lenght ones. So I'd reccomend the BBK unequal shorties. I've had mine for over 3 years with no problems at all, and you can still see some of the chrome through the burnt orange and blues
Have you considered pulleys? they're a great bang for the buck. your charging system should be fine since you have a SN95.
Since you can let the car sit. Why not pull the heads off and port the crap out of them. Those heads can be made to flow incredibly well. If you dont want to port them yourself then pull them off and have them ported professionally for a few hundred. It'll be well worth it.
since you'll have most of the motor torn down to do that anyway, why not throw a cam in there as the same time. The Trick Flow stage 1 would do nice and it's pretty cheap.
good luck
