Final Parts List Confirmation

[Behold81]

So the job is to replace my heads and put in a camshaft while at it.

Here is what I think I need.

Camshaft
Pushrods
Springs
Head Gaskets
Head Bolts
Water Pump Gasket
Timing Cover Gasket
Crank Bolt
Valve Spring Compressor (any cheap options?)

I have
Heads
Rockers
Rocker Cover Gaskets
Intake Gaskets
Coolant

What am I missing. I appreciate more could be replaced at the same time. unless essential this is what's happening. Its Gaskets and seals and other obvious things.

Want to put the order in by end of next week if not sooner.

Thanks all

Possibly:

COMP 4680-16 LS Spring seats
COMP 623-16 7* valve locks
COMP 511-16 Valve stem seals

Are you going Ti retainers or keeping the originals?

I only include those items as most 'kits' you buy include those items, and they're cheap.

Lifters and lifter trays are an easy swap and good insurance whilst the heads are off. I can't remember the outcome of your other thread what the concensus was on lifters, generally seems to be swap them while you're there...

Trunion upgrade for the rocker arms?

Have you seen the backlash against these on ls1gto? Bronze bushings are the new recommendation...or OE and pray. My Summit ones will be out soon, will see how they look.

I have not, not had much time for car stuff recently, that's very interesting as I'm likely to be doing a top end refresh some time (hopefully before Le Mans next year!) and just assumed trunion upgrade was the thing to do...

Any particular threads or shall I JFGI?

This one. I've got some Straubs incoming FWIW.

edit: actually, was thinking of this one on ls1tech.

Off the top of my head:

Spring retainers/locks/valve seals as sturdy said
LS2 lifter trays (unless you're getting fancy tied lifters)
Two water pump gaskets
Consider ARP crank bolt and studs (or bolts) for the heads

Tools:
variable length pushrod
spring micrometer (poss. not needed depending on heads/springs)
clay to check piston/valve clearance
alignment tool for front cover (nice to have)

I was thinking outside the box - pity it was the Wrong Box

[Behold81]

Thanks so far. In response to you all.

I'm looking at the BTR kit. either all from BTR or someone on here has some of the bits.

But its:

CCP Jam Cam
Ti .660 Spring Kit (Comes with Retainers, Guides and Seal)
3/16th 7.400 Pushrods.

Looked at ARP Studs and can't justify the cost over some throw away bolts for now. might get a crank bolt though.

Gasket comes as a set with timing cover and water pump gaskets(<Plural just checked)
What about a new Cam retainer Plate?

Have some YT 1.7 Rockers

Should my pushrod length really change? stock LS6 heads and gasket should be the same length.
Spring micrometer. I saw this. is it really needed? Would I not need spring shims as well? is this not for super fine setup?
Clay is a good point. but I assume that the CCP cam fitted to many LS1/6 vette's have had no issues so should be fine. I believe its a 0.6 ish lift cam.
Alignment tool for the cover? not seen that before.

Finally lifters I will not know till I'm in there but it is another expense. my lifters are quiet right now and I will look while in there. if they are bad I can pause, Order and continue. its not a set weekend job. Same could be with the timing chain. while in there I might see its worn more than I would like.

Definitely valid if it was a monaro. I hear its a consumable.

Respectfully, you need to do some reading and convince yourself as opinions will vary, but I don't think many people will advise gambling on pushrod length. If your LS6 heads are used, do you know how much has been milled/decked off of them? Are you having them resurfaced? Do the YTs alter things? Best to check.

The lift on the cam informs your choice of springs. Current thinking is choose springs with +.050-.060" as getting close to coil bind provides damping, which reduces valve float. Sounds like your spring choice would work well if the jam cam is .60"

Spring micrometer? I'm guessing probably not since standard heads, but again best practice to ensure installed height is good and forces as you want. I'm not sure how much science you can apply to choosing spring rate to be honest...other than "I have float, need more spring..." (or shim closer to coil bind?). Like with the timing cover alignment tool I'm mostly providing ideas for you to research and decide for yourself.

All just based on reading around...pinch of salt, DYOR, etc. I am sure someone will be along to correct me shortly

Buy a complete cam kit.

Water pump gaskets are re-usable.
Timing cover gasket is re-usable.
Crank bolt should be replaced ( although I've re-used them before with no problems. Or buy ARP )

Your heads are off, pretty much any typical valve spring compressor will work.

eg




You could replace exhaust manifold gaskets...but again, these are re-usable.

Get some M16 threaded rod and nuts/washers to help pull the front pulley back on. I would not use a bolt to do this

thought about this. but read that on a stock pan can cause issues with starving the pump.

Not sure on how true this is. As to lifters I will look when its striped if they look shoddy I will stop and replace.

I appreciate your comment. The ls6 heads are stock and do not look like they have been milled. I could probably check this with some digging around for data.
The YT rockers are stock replacement to work on stock heads. so these do not alter the rod length. they do have a shim option if needed.

I thought a very small change in thickness is not disastrous as there is a little play to work with.

the springs are what are recommended by BTR to use with the Jam Cam.

I will look in to the timing cover alignment tool. Honestly I never new it was needed. although there seems to be a lot of methods on setting it right. .

I feel a little sheepish. I have a standard Valve spring compressor. had not thought of the raised end style so it will actually have the clearance!

I know about not using the bolt to fit the crank. I have a longer install bolt I believe from when I bought my pinning kit. (That's going to be interesting to re fit. hope the dowels

I might get a gasket kit anyway as they are cheap.
Bolt will be ordered.

Crank balancer seal?

[stevieturbo]

The "shims" with the YT's...well washers really are for altering height to try and correct swipe pattern as some heads seem to have slightly different rocker platforms or installed valve heights etc.

Pushrod length will depend on rockers, these heights and of course base circle of the cam, so it is best to measure what is needed where possible.

It would do no harm to replace the crank seal, but again not essential unless there was something actually wrong with it.

And again, dont waste time/hassle fking about piecing together dozens of separate parts. If you're buying a cam/springs blah blah blah, just buy a complete kit from someone. They usually do deals and then there will be no excuse for any parts mis-match or incorrect selection.
Which if you piece it all together yourself...if anything is wrong or there is a problem it's tough luck on you.

Ill confirm with BTR on the rod lengths for a stock LS1/6 that match there cam. They give options on Spring and Rods. but it essentially will be a full kit.

Surely shiming(adding a washer) will need a slightly increased or decreased rod as well?

Or is that within tolerances?
