Pulling heads
#21
Yeah, plus engine assembly lube, possibly a timing set, timing cover gasket, 3 jaw puller rental, possibly harmonic balancer if you find a groove worn in yours, then pushrods. Plus, you'll have to pull the radiator and move the AC condensor. I'm not saying don't put a cam in, but, if you do, you might as well buy better heads while you're at it.

Remove the front bumper fascia, drain coolant, remove fans and radiator, condenser will already be unbolted (from rad. removal) it just needs to be angled out of the way, remove belt, waterpump, big 1/2" or 3/4" breaker bar to get the crank bolt off and a Harbor Freight puller to get it off , remove timing cover, line up the dots, unbolt/remove cam gear, let chain fall down (its not going anywhere), spin the cam to set the lifters up and install 5/16" wooden dowels so they don't fall (disregard if removing heads), unbolt cam retainer plate, temporarily install 3 waterpump bolts into the cam to help guide it out. Then reverse.
I did it in 3.5 hours with my Maggie, granted, I work pretty fast, but it will probably take you longer to get your heads off than to do a cam swap.
Also, don't mess with the broken bolt...the machine shop can weld to it if you don't **** it up too bad and wrench it right out...takes like 5 mins and they usually charge $25/bolt. If you booger it up, they cannot weld to it.
Some of the other stuff that has been tossed around....
- LS7 lifters...Yes yes yes!! Cost $110 (PN 12499225) and are well worth the money. Besides, OE lifters always seem to go bad after you have opened up the motor for some damn reason.
- Cometic gaskets....hell no. those damn things are like $80/ea +. Here is what I used when I pulled the heads with my Maggie.....GM PN-12589226 - hd gasket $17.57
- Trunion upgrade...not needed unless you have an early LS1 or a high lift cam (by high lift, I mean well over .600" lift). If you stay right around .600" or below you will not have an issue.
- Assembly Lube is not needed unless you are replacing crank, rod, cam bearings. Roller cams and roller rockers do not require this. I usually dunk everything in SAE 30 or 15/40 Diesel oil before assembly and have never had an issue. I know people that don't even do that.
- Springs and valve seals...Yes! Even if you don't do a cam, OE "Yellow" springs are like $55 and can be replaced easily with the valve seals. Would probably take you 1 - 1.5 hours to do it yourself for the first time.
One thing that I would recommend is to replace every TTY bolt with an ARP (head bolts, crank bolt, etc) since they do not add to the cost much over OE when replacing them.
My $0.02.

- Cheap
- Proven reliable with high lift/duration cams
- Cheap
- More consistent oil metering than older OE
- Cheap
When installing the LS7 lifters, you will need the LS2 style trays...GM PN-12595365 - lifter tray $5.51 (4 are required)
BTW - I think that was $17 for the head gasket set...not each.

Cam is relatively easy install as well as you don't have to pull the motor, just pull radiator and drop condenser as was mentioned above.
Timing cover gasket is only $15:

Asembly lube for the cam $5:
http://www.ebay.com/itm/Comp-Cams-10...0a3441&vxp=mtr
I got an IWIS timing chain for $50 (depending on your mileage may not be necessary):
http://www.ws6project.com/user_stor/...-timing-chain/
Also got my lifters there $130:
http://www.ws6project.com/user_stor/...e-ls7-lifters/
Head Gaskets cost me $40, here is Jegs on E-bay:
http://compare.ebay.com/like/4002810..._lwgsi=y&cbt=y
Harbor Freight of Jaw pullers $19:
http://www.harborfreight.com/3-piece...-set-8832.html
Harmonic balancer $58 (probably won't need, but still cheap):
Push rods run about $100, I like Atlantic Speed as they can also sell you a Cam:
http://www.ebay.com/itm/COMP-MAGNUM-...651d32&vxp=mtr
You can tell by all the links that I'm a cheap bastard and like to save money wherever possible, hence ordering from 20 different places. But you can really strech your cash that way.
The lube I was referring to earlier is the ARP assembly lube for the bolts, not engine assembly lube. If you bought the head bolt kit it comes with a small package of grease inside.

I know this isn't the most budget-conscious of me, but would lightweight pushrods be a good idea?
Also, when removing the PS head last night I noticed a LOT of carbon buildup on the piston head. What's the best way to clean that off? I tried some carb cleaner (what I had around) and a rag, but that didn't do much.

Having said that, they respond quite well to considerable camshaft lift and compression. The down side is all the supporting mods, timing chain, cnc porting, valve train upgrades, piston notching and tune, etc.
Where do you stop, and at what cost?
IMO go for reliability and get all the depreciation out of what you have now.
The best time to buy something is when you don't need it!

Its not for fit, its for durability. Older LS1/6 trays have been known to allow the lifters to turn in their bores, destroying the cam, lifter, etc. Cheap insurance.
#36
Yes, good call. Forgot about those, very cheap insurance. Had to buy a pack of 5. I can donate the extra tray but shipping would probably be more than buying new.

So, it looks like I'll be ordering:
LS7 lifters
LS6 springs
Comp's Trunion upgrade
LS2 trays
MLS head gaskets
Intake manifold gasket
Already ordered ARP head bolt kit for $109 shipped off ebay.
Will I need new valve cover gaskets or can those be reused?

I've had good luck with B-12 Chemtool fuel system cleaner, wipe it on and let it sit for a while and the carbon wipes right off.

Gotcha, thanks for clarifying. Torn knees are bad for driving stick.

All the gaskets are reusable other than the head gaskets. I replaced mine on the Vette at 103000 miles because I am old school. Just do a good inspection including the rockers.
You don't need the Comp Trunion upgrade unless you are running .600 lift or more. I would put that money toward new exhaust valves as they get brittle with mile. My grandson dropped one on the floor and it shattered. FYI.
I would suggest using LS6 lifters as they are designed for your motor.
