Parts required to lift and replace heads ?

Hopefully, I've not overlooked anything for next weeks job. However, given my track record. I thought I ought to ask......what parts , apart from consumables such as oil, coolant , filter , are needed for lifting and replacing the heads on an LS 2? I'm putting lifters in ,so have the following to hand;

1. Lifters . Summit LS 7 's with their lifter trays.
2. head gasket/top end set. Felpro LS set.
3. Pushrods. Just in case, but can't hurt to swop 'em out whilst diving in there. Brian Tooley racing , stock length.
4. Head bolt set . Summit O.E.M. spec set.

What have I missed? Surprise me and tell me I have it all !!

Does the gasket set include the intake rubber seals, I know they’re reusable but at probably 15 years old I’d change them they’re going to be pretty hard by now.

Would be a good time to replace the sparkplugs
Depending on condition to also replace the bolts for the exhaust manifolds
I assume that kit comes with exhaust manifold gaskets and the ones at the bottom of the intake manifold ?
Why are not changing the rockers with like higher ratio roller type ?

Having the correct process to install the new torque to yield head bolts and a good torque wrench ?

Not sure if there is enough movement when taking the exhaust manifold off heads, that exhaust drops enough to get the heads off
or having to take exhaust pipe off at CATS, if so need new donut type gaskets ?

If not having this

NOTE : Keep in mind the head bolts are torque to yield type and cannot be reused !

Using a socket wrench and lightly turn the bolts until they stop. Now for the very precise part.
You need to get your torque wrench out now and fit it with a 3" extension and a 15 mm socket.

Using the sequence illustrated below, torque all 10 15 mm bolts to 22lb-ft.

Now take a felt tip marker and draw a horizontal line on the head of each bolt. This is very important.

Next, using the sequence illustrated, turn all 10 15 mm bolts an additional 90 degrees using a large socket wrench and a lot of muscle.
Try to get as close to 90 degrees as possible, you may have to do multiple turns of 30 degrees or 2 turns of 45 degrees.
When done, all the lines on the bolt heads should be totally vertical.

Next, again using the sequence, turn bolts 1 through 8 another 90 degrees.
This will take an immense amount of effort...if you have a buddy helping, both of you should turn the wrench simultaneously.
These 8 bolts will now all have horizontal lines on them

Using the sequence, turn bolts 9 and 10 an additional 50 degrees.
Again, this will take a lot of effort. 50 degrees should result in a diagonal line on the bolts

Finally, using the sequence above, torque bolts 11 through 15 to 22 lb-ft.

Yep,
got the intake gaskets, the cars an 06 so they won''t owe me anything by now. The rockers are 1.85 ratio , as the car has the SLP ZL 465 kit on it. Hence the header/collector gaskets are likely different from stock also , if they're needed , don't know what will happen there. Halfords won't have 'em !! Hope the headers will give enough clearance once the flange bolts are out. Plugs I'll change myself soon. They're a damn sight easier than my C4 , for sure. It's not actually me doing the work , I have no undercover facility , and given it's been windy a lot 'round here, I wouldn't want all the airborne crap to get where it shouldn't. Also , I am tied up every other day with my missus at dialysis , so a day on, a day off would be a bit ropey. Ironic , really, as for a modern car, it doesn't seem too complicated ,unlike my daily smoker. Easily within my capbility .So it seems I have all the parts, then. Just got to cough up the labour at main dealer rates. Yikes !
