Default 3.4L/3400

Hey everyone,
I've been looking into doing this swap for a long time and I finally feel confident enough to give it a shot. This engine will be going into my '95 Camaro with the 3.4L obviously. So far my build plan is:
2000 3400 Upper Plenum-- Check
2000 3400 Lower Plenum-- Check
2000 3400 Throttle Body-- Check
2000 3400 fuel rail + regulator-- Check
2000 3400 Fuel lines-- Check
3.4 Water Neck (British Car Conversions)-- Wondering if I can just use a longer house?
2000 3400 Heads and Valve Covers-- Check
Pacesetter Headers-- Waiting
3400 Spark Plugs-- Check
Dual wire Temperature Sensor-- Waiting
3.4L Block-- Freshly machined block
3400 Pistons-- Check
Custom Cam-- Check
Custom Pushrods-- Check
Comp 26986 Springs-- Ordered
Comp Flat Tappet Lifters-- Ordered
Double Roller Timing Chain Set-- Ordered

I believe that I have to change to the 3400 pistons to run a safe CR, so if anyone can confirm that I'd appreciate it. But just out of curiosity, what would the CR be with the 3.4 Pistons? And other than a junkyard, is there anywhere that sells stock 3400 pistons? As for gaskets I'm not too sure which ones I need so anyone who can help me with that I'd appreciate it as well.

I think I have the tuning part figured out for the most part. I was pointed towards Tunercats who recently came out with support for tuning the 3.4L Pcm in win flash. I feel like a couple of tuning tutorials and I should be able to figure it out.

There's still a few more things I need to decide on and was hoping I could get some help from you guys. For the cam, I've been debating on running the Comp 260H or 252H High Energy Cam, along with 1.6 Comp Rocker Arms with the Hardened Pushrods but I'm not sure if I'd be able to use that with the set-up I described above so any help or guidance you guys can give me is greatly appreciated!

Thanks in advance!
