Question / opinion top end rebuild with upgrades Hey everyone.
I have a 2002 WS6 engine paired with a TH350 in my Nissan 240sx. The other day the water pump went on me (leaking from prop o ring). So I took it off and started to get it all cleaned up for the new one to go one. While it was up on the stand I decided I'm going to change the oil. I drain the oil and its milky. So I pull the timing cover, and rails and intake, but not the heads yet. I dont see any crack or leaks, so I'm thinking its gaskets. But I am going to check the decking before I do anything.
But if all is good and the timing cover is off, WP is off, heads are off, why not upgrade.
So I have a set of 241's, 243's, and 317's in my garage. So more then likely ill use the 243's with a stage 2 port and polish.
I am looking at the thunder racing cheater cam, 214/230 .601/.575 117 LSA
Dual Patriot Extreme Valvesprings and Ti Retainers
Thunder Racing Pushrods (7.400)
Valve Stem Seals
The 317 heads have 3600 miles on them so I might steal the rockers and valves from them.
But other then gaskets, oil pump, and cam chain / gears, what else should I get? I see ARP sells heads bolts and a stud kit, which one do I need? And am I missing anything else?
Im trying to price it all out so I know what to save for and how much OT to do this month.
What kind of power should I exspect with this setup? Its on a 2800 Stall, with a 3.689 gear ratio on a LSD

Head studs will be aftermarket and are reusable. The ARP bolts are also reusable. OEM head bolts are not reusable. They are TTY and are for one time use. Some people recommend LS7 lifters, and some recommend Caddy lifters. I have stock lifters in my car.

Ok so studs and bolts are on the list.
What about these 317 heads I have? They were pulled off of a cargo van that rolled over 3 weeks after it came off the lot. I picked them up in a trade, and don't know what to do with them. Worth using, the 243's have close to 90K, the 241's I have are on the motor now and have about 55K on them.
Im just not budgeted for heads at the time, but depending on porting, polishing, and milling price I may just have to add them to the list.
