the timing chaing is probably more important than the oil pump. i wouldnt really worry about it if your on a budget, just a good piece of mind, i know plenty of guys with heads/cam cars that are still running on stock oil pumps

lifters, springs, pushrods

will need prom re-programmed, will heads support the cam, do you have enough exhaust to support cam, enough fuel delivery?

Your going to have to remove the oil pump to get the chain off. So why not?

You don't have to but I highly recommend it. Those stock LS1 oil pumps are a POS and if your going to do some racing I would go ahead and spend the extra $110 and get a ported LS6 pump. I think my oil pressure runs about 40 psi at idle and 60 psi at higher rpm on my LS6 pump. Cheap insurance if you ask me.

The oil pump is worth the few bucks for peice of mind.

How many miles on the car and what cam are u going with? That'd determine if its worth to pull the heads and do the lifters also.

Maybe someone can put this to rest for me; On an 02 Z, what parts were upgraded? I know it has the LS6 intake, but I've also heard that it has the LS6 Oil pump, is that true? Anything else?

I absolutely agree. The last thing you'd want, is to go through the entire process of installing a new cam.... then have you're stock oil pump go bad on you a few months down the road, only to have to take everything back off all over again. Change the pump now, for peace of mind's sake.

I did anything and everything with my new motor.
New COMP timing set, new LS6 ported oil pump, new pushrods, new springs.
The only thing stock in my motor right now is the rocker arms. EVERYTHING else is aftermarket.

I idle at 925 RPM's. Oil pressure is at 42-44 PSI at idle.
