Cam and Heads install

im going to be putting a cam and some heads in my car soon and was wondering if there is anything else i should or need to do

so far i have a the heads, cam, and gaskets
im ordering some stock ls2 head bolts

i drive this car everyday and dont really want to replace the converter

what heads did u get? you should do underdrive pully while your in there and maybe think about a fast intake

Depends on the cam, but you might have no choice but to get a higher stall converter.

agreed. i have not heard of too many goats that have a cam without a higher stall converter

they are et heads and a small cam

How small is small to you? Most people consider anything around 220/224 to be small, but I think my cam is the definition of small.

You may already have this stuff, but just in case
- hardened pushrods
- valve seals
- springs
- tool for holding lifters in place
- tool to compress valve springs
- hose with fitting & compressor to hold valves in place
- assembly lube for cam, pushrods, rockers, timing chain, etc...
- extra rocker arm bolt or two (in case you accidentally round off the shoulders during removal)
- coolant
- oil filter & oil
- new crank bolt (ARP or GM)
- GM manuals came in handy for me as well...

Hope this helps!

i dont have pushrods or a new crank bolt. what do i need those for?

The crank bolt is TTY and should be replaced everytime it's removed. Hardened pushrods should be swapped in everytime you change to stiffer valve springs, because the stock pushrods will flex too much at higher RPM.

all good advice. i would also upgrade the head bolts. i know stock ones will work fine but if you are changing everything else why not those also.

PLEASE use arp head bolts.

Stock pushrods much better. I would rather a bent pushrod then head/engine damage any day of the week

ARP head bolts are just so much easer to torque

alright thanks now i got a better idea of what i need im defintaly gonna pick up some pushrods

do i really need arp head bolts over the stockers? i can get stock for $26 a side and arp are like $150???

Yeah, get the ARPs. There were installed at the time of my heads, cam, intake, tb....

is there any advantage to them or just easier to work with?

Very bad advice. YOU WILL NEED NEW SPRINGS AND PUSHRODS
But, hey.. It's your motor.

I'm stockpiling parts for my heads and cam installation next month and once my injectors come back I'll have everything.

This is my list:

Cam
Advanced Inductions cnc'd 243's
Patriot Extreme spring kit
Pushrods
SLP high volume oil pump
double roller timing chain set
Resized LS2 injectors
ARP head bolts
Grade 8 locking header bolts
Crank bolt
Head Gaskets
Water pump gaskets (there are two)
Exhaust gaskets (the originals are reusable)
Front timing cover gasket
New spark plugs
Assembly lube
Antifreeze
Street Tune

You can getaway without some of these items. I'm anal about my car, the parts used on it and as a personal preference prefer to hit everything on the first attempt.

I don't think bigger injectors are needed for you setup.

My setup works fine with the stock injectors.

stock injectors will work all the way up until 100% duty cycle but would you trust your motor to countless WOT runs at 100%?, 95%?, 90%?

I don't think you will find a single sponsor here that would do a head cam build in house and not recommend a larger injector.

FYI you can have stock LS2 injectors re-sized and flow matched for a little more than $200.00 Pretty cheap insurance in my book! on top of that, they are already off the car and your already paying $$$.$$ for a tune why not get your injectors into the sweet spot of around 70% on the first attempt, tune it once and be done. When your tuner says you are at 90+% and that they should be replaced not only are you going to spend the money on the injectors, there is now unnecessary labor involved and you gotta fork out at least $200.00 for another tune. Seems back woods to me

ARP head bolts are $99.00 from vendors here on this site.

Hmm. The sponsor I dealt with never mentioned them as an issue. Here are my mods in my ownership thread.

Didn't see a front cover seal on your list. Some people say don't mess with it, some do.

I changed mine when I did my cam swap. Just something else for you to ponder...

I would think 42's would be large enough. I had my stock LS2 injectors re-sized and flowmatched to 48 for $210.00. You should ask whomever is doing your tune or seek the advice of one of our sponsors that does a lot of H/C GTO's. CAll FRAN at RPM he does nothing but LSX powerplants and a lot of LS2/LS3 GTO and corvettes. That or maybe seth at Hinson could help.

My tuner has a 500+ wheel HP vette with injector much larger than 48 and he still gets 24ish highway MPG.
