Rebuilding/Upgrading LS1
The lifters are so noisy that it's time to replace them. I know it's not an LS6, but while I'm at it and need to rebuild the engine, I might as well upgrade things.
This will mean I will want a different cam and as such different springs, lifters, retainers? If I am aiming for 450whp what path should i take?
I need it to be reliable under harsh driving, road racing.
I would like to keep it low on $$$
These engines have been around so I'm sure people can chime in with the typical builds.LS6 heads or something better? What do heads come with? What cam would you guys suggest? What lifters/retainers/valves? Do these come with some head packages?
LS6 intake or Fast Intake? Fast is obviously more $$$

That's a fairly high number, I think a fairly simple build with a SC would be best/easiest.
So I'd say talk to a cam company (Tooley for example), tell them your goal and what your motor consists of. Other than that pick a good SC, headers, eliminating the cats is often advised with FI, CAI, Fast intake, 243 heads at minimum and a good motor once over by somebody who knows their crap.
Going to somebody like Texas Speed, Tooley etc. and buying a supercharger package might even be your best bet.
How many miles on the motor?
I bought the car with 139,000, now at 156,500. Summer car, driven hard

The lifters sound horrible, so I want to upgrade these components, put in a cam and any supporting mods to get there.

Is this the head you used http://www.jegs.com/i/AFR-Airflow-Re.../1530/10002/-1
The spec sheet is confusing, does it come with arp studs, felpro gaskets, or are those all suggestions?
Mighty expensive yikes, I am assuming it came with everything included lifters, springs, valves, etc... and was just a drop in job?

Have you considered having a shop in the US do the work for you?
I don't know how importing stuff across the border works, but do you have a friend here in the US who can receive all of your goods; and you can go and retrieve them?

Not the cheapest route but for sure not the most expensive(I couldn't swing big dog heads that were twice the cost of the trick flows for a few more hp).
What really kicks you in the weiner moneywise... is setting up all the little things right. BTR platinums w/ Ti retainers, C5R chain, Johnson 2110 lifters, Manton pushrods, cometic .040 head gaskets etc etc etc. Don't skimp on your valvetrain. You see people paying that price on here everyday from using cheap lifters, flimsy pushrods and the wrong springs.
BUT you do it right once instead of cheap twice. IMO doing the best heads and intake you can afford will get you the best results. You can do great heads/intake with a **** cam and still get good numbers. Don't work the other way around.

I had BTR .660 dual springs, dual chain, LS7 lifters...heads milled to .59cc, cometic .040 head gaskets....etc...

Replace the lifters, refresh the heads while they're out, and slap a 100 shot on it. Follow up with LS6 intake, longtubes, etc.
The "right" way to do it is spend a lot more money, on a properly spec'd system - cam, heads, valvetrain that will all work together.
So lets say my concern is to have something rebuilt/strong/reliable that can be ripped on at redline regularly...summer daily driven on highway, heel&toe through corners, track days.
I would be looking at upgraded trays, lifters, pushrods, valves, springs. I am pretty sure my lifters and springs are garbage by the sound being made.... and so if i am doing that and i consider some head package... it would be ideal for me to get something high end in terms of lifters and trays.... get a head package..
Fix PCV oil burning issue (I read about that something LS6 have resolved), and relocate oil pressure sensor (its gone bad too... i hate that...), i was told there is some kind of relocation kit since its hard to reach wit hthe intake needing to be taken off.
oil pump would be smart to do too..
What else?
Something I'm thinking about, as I want to do about the same (98 LS1):
LS7 cam
LS2 or LS6 complete heads
LS6 complete Intake manifold modified to fit 90mm throttle body
LSA oil pump
C5R Timing Chain
and all the little stuff around. oil sender relocation, new belts, tensioners&pulleys,...
cheap and reliable makeover and some HP gain...

Does it come with pushrods and rockers? Comes with what looks like upgraded valves, dual springs, TI retainers, obviously all the tiny valvetrain stuff like stems etc... What about rockers? Anything else?
Anyone got input on it.

As far as lifters I was looking at these:

Not sure what the dif is between this one:

Appears to have that linked bar thingamajig. I heard these link bars make noise. However I was told these slow leakdown lifters are very quiet.
