Parts list for rebuild/headgasket job
So at the end of the season last year, I popped the head gasket. I have a parts list/minor upgrades that I wanted to throw out there and let me know what you guys think or what I chould change/add. This is for an 09 px with the current mods in my sig. Thanks in advance.
OEM head gasket
ARP flywheel bolts
Rocker shaft bolts
Eastside powersports cam
upgrade thermostat to 160 degree
cam lock tool
crank lock tool
Oil change/plug maint. kit
Supercharger tebuild kit
This is what I was looking at for this round. My question besides if I am missing anything is, is the cam a good idea now, or would I be better off with supertech valves instead? I don't mind spending a little, but I don't want to go crazy since I am looking at a CMD with auto tune to get my fueling under control.

that's about right. The cam is a good idea even when you're stock with an intake IMO. You need to get the head checked for flatness while it's off.
BTW I have the T-Stat for sale if you want it. On the cheap too.

I actually work at a dyno lab that specifically tests head gaskets for OEM, so this is exactly what I do daily. I have been reading up on the mercruiser t-stat modification, and figure I will attempt it. If it doesn't work, I will be in tough Imposter.

it works and is what I have for sale. Just be careful splitting the housing and when you put it back together use some kind of epoxy and a worm clamp for pressure.

When you remove the T_Stat from the housing be real careful as they can get very brittle and break easy. I get three small Screw drivers and I put the head of the Stat in hot water to kind of make the plastic more forgiving. then I put the screwdrivers where the tabs are and it will pop out with little effort. the when I reinstall I have used three set screws, or epoxy or just a worm, clamp. Very simple and about a $20 fix.

You have the head off already so if it was me I would do valves before a cam.
Cam and springs can be added without removing the head. Valves can't. If you only have funds for one or the other I would recommend valves first. Other stuff later.

get REV and keep the awesome multi groove keepers if you decide on valves (good choice).

I assume a cam would do more than valves. I am at the point where if I did any more work, I would be doing a turbo and completly changing my set-up. With that, will the cam be a better spend of money than the valves? I am more interested in gaining RPM and not acceleration.

Lightweight valves and better springs and you can run 9200 rpms possibly more.
You will need no up the Rev limiter.
