04 350z head fitment....
Okay, I maybe able to get my hands on a set of 04 350z heads with head work done for a decent price. I just wanted to verified that it'll fit fine on my 02 3.5. This may be a dumb question but its late and I can't seem to think straight, I think it will work since its not from the revup motor which are 05+. Correct me if I'm wrong. Thanx

BTW, you should get a 350Z head gasket. They have 3 layers as opposed to 2 in the FWD VQ's.

If I do get this head, it already has the following:
04 heads with jwt springs, valves, retainers, and shims. Pocket ported, decked and 5 angle valve job.
Well here is what the plan is for the moment:
Arias 8.5:1 Forged Pistons (oversized 96mm)
Eagle Rods (havent decided on stock or nismo rod bearings)
Bottom end will be balanced with at least the pulley if not with the flywheel also
ARP: Rod/Main/Head bolt
HKS Head gasket
JWT C2 Cams with JWT springs/shim and cam spacer
REVup Oil pump
PF TB and adapter
Some minor head work (3 angle valve job and mild p&p) if I don't get the head.
Modified IM (SSIM style)
J&S (already have)with EU
Tranny work
I know there are better pistons out there and probably better things but I just want to get a decent build(engine) and not spend more than 5k which from my calculations is about how much this is gonna cost me.
If you guys have any suggestions, please feel free to share. Its gonna be a winter project and I dont plan to have it running til at least March but I figure if I'm gonna do it, I may as well take my time and go easy on the wallet

I wouldn't bother with the JWT valvetrain.
Check these out

These will work with either VQ30 or VQ35 heads. Double valve springs FTW. Fearra and NISMO also makes a kit but theirs cost more.
Also I dont think its possible to do a 5 way valve job on VQ35 heads, Cosworth sells reworked VQ35 heads and they could only do a 4 angle intake and 3 angle exhaust.

Thanx. I'll look into that. Do you think the stock retainer will work with dual valve spring? Would I still need the shims to work with the JWT C2 cams (especially when they are required)? $520 might be out of my budget but the springs look promising.
The Nismo ones aren't bad either at $279.

You would have to reshim, even if you were not doing a valvetrain build up you should still check & adjust the valvetrain regardless of what cams you run.

Ben should be the new sales asst. for J&S I have a feeling he would do very well.
BTW justin. Your getting CP pistons.

The thing even breaks loose the tires going into 3rd gear.
I need to get some damn time to work on these little things. Right now, I borrow the license plate from my beater 95 maxima with 200k miles when I want to take it for a drive.

motor swap is the way to play. Unless you get a supercharger, but thats not to my liking. I'm planning on doing the 3.5 swap in my 2k hopefully by next summer. You can do port n polish if you want....
