Ok the engine isnt out, but am planning on doing a little winter project....or back to school project. Whichever comes first. I will be putting a hot cam and lifters in, replacing many gaskets (I have many oil leaks) and taking of manifolds AGAIN and fixing the stripped threads in my heads. Should I go the extra step and replace psiton rings or anything else while this is out? Thinking of N2O in the future.

Definately do pistons and rings, good insurance with no2

Freeze plugs. They are in between the engine & the trans. Not expensive and pretty difficult to replace later.

Better injectors.

The Engine.

Or at least port the Manifolds.

save your money and buy a good used 3.4 out of a pre 95 camero. just need to drill the starter holes on the opposite side of the block. Good for about 20hp over stock and it has a much better oiling system.

install exhaust manifold studs

replace water pump with NEW pump (not rebuilt)

Run a tap through the threads in all threaded holes in th block and dab a bit of antisieze in them

remove and overhaul the distributor. Clean all the built up gunk off the shaft so it spins freely. Install new distributor o-ring and maybe even the ignition module and pick-up coil.

Port intake and exhaust manifolds.

Inspect/repair all vacuum lines.

Replace all 7 fuel injector's o-rings.

Thoroughly de-grease and clean engine and wiring harness.

Remove A/C and alternator bracket and run a tap through the internal threads and dab a bit of antisieze in them.

Spark plugs, check the exhaust manifold for cracks, replace with hedders.

And go with Forged pistons when using NOS
